I had the same problem a couple days ago. I solved it by disabling UCSS. It’s an online service by LiteSpeed / QUIC Cloud that basically rip off unused CSS class after CSS combine executed.

Thanks for replying my message, the files ares quite confidential to share it here on the forum. Is there anyway I can send my OneDrive link containing the files to you without exposing it here?
Okay, I’ve excluded the login page and register page in my LiteSpeed Cache plugin, but still it doesn’t work.
Any other thoughts?
