I've searched for posts related to the same issue, but everything I've tried doesn't work.
I have tried installing a caching plugin and excluding the website from the forum.
I have tried to enter a code in the forum settings css, but I don't get anything and I don't know what I could be doing wrong.
(I have used the Google translator, in case some strange phrase appears lolol)
Attached file where the icons of the themes do not work. Thank you 🙂
Thanks, that was it. Thank you so much for everything.
