Typo3 Mask – Javascript and CSS includes of extensions missing

Filed under: JavaScript,Typo3 — Tags: , , , , , , — Christopher Kramer @ 11:36

I was using Mask 2.1.1 with Typo3 7.6.11 for a site as described in the Mask manual with this typoscript:

page <
page.10.file.stdWrap.cObject.default.value = fileadmin/templates/index.html
page {
        includeCSS.styles = fileadmin/templates/style.css

The problem with this was that the CSS and JS files includes from extensions where missing, even though the static templates of this where included. The reason is that this typoscript overwrites the page.include* stuff defined by the templates.

A workaround

To solve this, I copied the page.include* stuff defined by the extensions in a temporary variable and restored it after loading the mask object into page:

tempJSFooterlibs < page.includeJSFooterlibs
tempJSFooter < page.includeJSFooter
tempCSS < page.includeCSS

page <
page.10.file.stdWrap.cObject.default.value = fileadmin/templates/index.html
page {
        includeJSFooterlibs < tempJSFooterlibs
        includeJSFooter < tempJSFooter
        includeCSS < tempCSS

        includeCSS.styles = fileadmin/templates/style.css

There are more includes you might need to consider if your extensions use these:


Hope this helps someone with the same problem! Please let me know if there is an easier solution.

Update 06.07.2017: The clean way

So the workaround described above works, but it has a disadvantage: You might install a plugin that defines some other page.* property that gets lost. For example, I just had this problem with mindshape_cookie_hint: It defines page.9877 which gets lost when you overwrite page with It took quite some time until I found the reason for this problem. And then I found another way which is much simpler than the one described before:

page = PAGE
page.10 <

Just don’t copy the whole, only This will preserve all the stuff defined by plugins. The solution is so simple and easy!

So I think this is not really a bug in mask, it is rather a mistake in the documentation.

Please let me know in the comments if this saved your day or if you have suggestions.

Montezuma WordPress Theme: Solve Inline CSS

Filed under: PHP,Wordpress — Tags: , , , , , — Christopher Kramer @ 18:12

I was recently asked, why CSS changes within admin panel of the Montezuma WordPress Theme were not reflected on the frontend.

I found out that there is an issue with Multisites, but no solution. So I digged into the code to solve the issue. As I think it might be useful for somebody, I post here what I found out.

if you are not interested in technical details, just look for what I highlighted 😉

Montezuma theme uses inline CSS

If you look at the HTML Source of your site, you will find the whole CSS inline along with this text:

Default CSS served INLINE because wp-content/uploads is not writable.
This will change once wp-content/uploads is writable

So the issue seems to be simple: Just correct permissions. Something like this:

chown www-data:www-data wp-content/uploads

Unfortunately, this was not the issue here. So why does Montezuma fail to place the static CSS file in wp-content/uploads?

Invalid file type

It took me a while to figure out what Montezuma does. In save_css_file() in includes/admin.php, it uploads/stores the theme’s css using wp_upload_bits(). The first problem in the theme is that it does not catch the resulting error while doing this. It should at least print it somehow. In this case, this would result in “Invalid filetype” (in your language).

So wp_upload_bits() calls wp_check_filetype(). This will call get_allowed_mime_types() for a list of allowed mime types. And this looks like this:

function get_allowed_mime_types() {
        return apply_filters( 'upload_mimes', wp_get_mime_types() );

So it calls wp_get_mime_types() for a list of mime types. This will again apply a filter on a list of arrays, which in fact contains css. This is good news, because we want to store a css file…

So one of the filters kicks “css” out. And the short story is that it is upload_mimes. The upload_mimes filter uses a list of allowed extensions that can be edited by the user!

To edit it, open in your browser.  The list of allowed filetypes for uploads is quite at the end of the list of settings. Just add “css” here (space-separated).

I think Montezuma should better overwrite the upload_mimes filter with one that allows css.

If you now save your Montezuma settings, it should successfully create a file

But in a Multisite setup, this is not the end of the story.

Montezuma uses CSS per site (in a Multisite setup)

With a multisite setup, it depends in which site-backend you change the Montezuma css. If you login one site, it will create the css for this site. If you log into another site, it will create the css for this site.

So you need to change the css in the backend of every site.

So let’s assume you have a site “de” and a site “en”. Then go to and change the CSS in the Montezuma settings.
This will create a file like:

Then log into the next site and edit the css there as well.
This will create a file like:

Then the css as you edited it should be used in the frontend.

I guess Montezuma should add an option to use a global css for all sites.

Update: Similar problem: Google Webfont is not loaded

The theme allows you to easily use a google webfont. But it does not load?

The problem is almost the same: It fails writing the .js-file. So go into the network-settings and add “js” to the list of allowed extensions, save the Montezuma settings and it should work.

Oxwall Community Software: How to create your own theme

Filed under: PHP — Tags: , , , , , , , , — Christopher Kramer @ 14:45

Oxwall is a great community-software written in PHP. You can easily install it on your own server to build your own community site.

It is open source and you have full control over the data.

Although Oxwall comes with some great themes that can even be easily customized in the backend a bit, one might want to build one’s own theme for Oxwall.

So here is how it’s done:

  1. Probably first build an HTML template of your design (one HTML page with CSS that looks like you plan how your Oxwall should look like). If you do that, make sure to use a list-based main menu and a div/link-based bottom-menu (see below) so you won’t get into trouble later.
  2. Always a good idea to have a backup – although adding a new theme shouldn’t break anything. I’d recommend you to create a copy of your Oxwall installation where you create and test your new theme and when it’s finished, move it to your live installation of Oxwall.
  3. Create a copy of an existing theme. You will find the themes in ow_themes. Choose one you’d like to use as a base for your own theme.
    Copy it. E.g on a linux shell:

    cp -rp ow_themes/spring ow_themes/mytheme

    Of course you could also use FTP or something like that.

  4. Define the meta-data of your theme like name, author and so on. To do so, open ow_themes/mytheme/theme.xml in a text editor and adjust the data. Make sure the <key> is equal to the foldername (“mytheme” in the example).
  5. If you want to, you can replace the theme_preview.jpg with a small thumbnail representing your theme (optional).
  6. Now you can select this theme in the Oxwall backend. Try it.
  7. Note: To be able to adjust the theme, enable DEV_MODE. Otherwise you won’t see any changes. So open ow_includes/config.php in a texteditor. Search for:
        * Make changes in this block if you want to enable DEV mode and DEBUG mode
        define('OW_DEBUG_MODE', false);
        define('OW_DEV_MODE', false);
        define('OW_PROFILER_ENABLE', false);

    Change OW_DEV_MODE to true:

        * Make changes in this block if you want to enable DEV mode and DEBUG mode
        define('OW_DEBUG_MODE', false);
        define('OW_DEV_MODE', true); /* HERE! */
        define('OW_PROFILER_ENABLE', false);
  8. Now you can start to adjust your theme. So what does a theme consist of?

Meta-Data: theme.xml

Like said, theme.xml contains the meta data and theme_preview.jpg is a preview image.

CSS: base.css

The main css of a stylesheet is called base.css. You can change/adjust the css there (there are also other places like the backend). I would recommend you to keep the css of your base theme and only adjust and add things to it. Otherwise you’ll have a hard time styling lots of things.

Images: images/*

If you need to include images, this is the best place to put them. If you refer to them from the css, use a path like this:

background-image: url(images/myimage.jpg);

HTML: master_pages/*

The HTML that builds your theme is stored in master_pages.

Note: Lots of themes do not contain all master_pages. If one is missing, the master_pages of the graphite theme are used. Therefore, I’d recommend you to first copy missing master_pages from the graphite theme to your theme so you get a full set of master_pages.

The following master_pages can be there:

  • admin.html (only for the admin backend – no need to adjust this)
  • blank.html (usually no need to change this as well)
  • dndindex.html (body for  pages without sidebar – you’ll want to adjust this!)
  • general.html (body for pages with sidebar – you’ll want to adjust this!)
  • html_document.html (html-head of all pages, you might want to add css or javascript here)


The following are the most important markers that you can put into your html master_pages:




{component class=’BASE_CMP_Console’}

This is the console containing “Login”, “Register” and so on (usually at the top right corner).


A list-based menu.
Hint: Listamatic has lots of great list-based menu examples.



The sidebar.
Note: only in general.html

{add_content key=’base.add_page_top_content’}
{add_content key=’base.add_page_bottom_content’}

These 3 build up the main content.
Note: You’ll only need {$content} in dndindex.html


The bottom menu.
Note: Not list-style, but a div with links.

{text key=’base+copyright’}


{decorator name=’floatbox’}

This should be at the end of your html file – oxwall puts some JavaScript and stuff like that there (for chat etc.).

All the others should be self-explaining.

So how you could do it:

  1. Upload your images to “images” and your js (of any) to the theme-folder
  2. Add your css at the end of base.css
  3. Add your references to additional css / js to html_document.html (no need to add a reference to base.css!)
  4. Put the content of your body into general.html and dndindex.html
  5. Replace your static content in there with markers.

Don’t forget DEV_MODE

When you are done, don’t forget to set DEV_MODE back to false. Otherwise your site will load slowly.
