To make certain that you applied the style correctly, we recommend that you apply the style through the cPanel interface.
Navigate to the cPanel interface in your browser, and perform a hard refresh.
On MacOS® computers, press Command+Shift+R.
On Windows® computers, press Ctrl+F5.
Check whether the cPanel interface now displays a blue background. If it does, the styles.css file exists in the correct location, and the cPanel interface can read it correctly.
Check your CSS file for errors. If the problem persists and no errors exist in the file, you may need to submit a ticket with cPanel Technical Support.
Custom icons do not display
Your custom style includes custom icons, but the cPanel interface continues to display the default cPanel-provided icons, or icons from another style.
In most cases, this problem occurs because you did not run the /usr/local/cpanel/bin/sprite_generator utility after you applied the style. This utility integrates your icons into the cPanel interface's icon set.
To use this utility, run the following command, where mystyle represents the style name:
If this command does not solve the issue, confirm that you stored the icons in the correct location in your style, and that they use the correct filenames.
You must save icon files in the icons subdirectory within the main style directory. For example, if you created the mystyle style and applied it to all of the accounts on the server, icon files should exist in the /var/cpanel/customizations/styled/mystyle/icons/ directory.
To replace existing cPanel feature icons, you must use the same names and file extensions as the icons that you wish to replace.
For example, to replace the File Manager feature's png icon, you must save the icon as the file_manager.png file. Or, to replace the svg format icon, save the icon as the file_manager.svg file.
