my theme uses a dynamic css file 'custom-style.php' which is included through wp_enqueue_style(); This file includes some styles depending on the theme options (colors,fonts,...)
On some installation there is no access to this file. Trying to access the file via the source code gets a "500 Internal Server Error". Changing file permissions to 777 does not solve it.
How can I solve this? Is there any other possibility to create dynamic css files?
Alternatively I could write a function to include this css in the head of the html but this is not the way I want go. There are some lines of css and I don't like css in html output.
