Hi, Thanks for your response.
I did the test you requested, and I can say that the files are indeed deleted and regenerated with new names, without updating the changes I made to CSS files.
When deactivating and activating the plugin, the files are regenerated with new names and updated content.
I noticed another thing, which I do not know if it is a normal operation of the plugin:
After deactivating and activating the plugin the files are created with names starting with 0-css
and after trying to “clear everything” the names change and start with {10 digit number}-css
.
I do not know if this is indeed a bug but I am writing this just in case.
Awaiting your check, and thanks again for your help.
