Hello, can you send me the URL of your website so I can see what is going on? You probably need to set up file and/or folder permissions to the Trombinoscope module as the stylesheets are PHP files and not CSS ones. You probably lost the permissions when moving the files to a different server.

Thank you for the URL.
It confirms the files permission issue.
Check or make your server administrator check that the module files have 644 and folders 755 permissions on the server.
The file mod_trombinoscope/style.css.php must be accessible (it uses parameters in order to work).

You are welcome! Glad it works for you
