X3 Theme issues.. not working properly

I'm having a strange issue with X3 theme on my server. When a user logs into cPanel their icons are in a row, one on top of each other. Also none of functions, such as password strength indicator, work properly.

This happened a few weeks ago and I upgraded to CURRENT and the problem disappeared. Then today, I log into a customer cPanel and the problem has returned.

I tried x2 theme and it works fine. I took X3 off another server, deleted x3 and reuploaded it to the server and the theme still isn't working problem.

Just in case, I forced upcp and restarted cPanel. Nothing seems to fix the issue.

Anyone seen/fixed this?


cPanel Version 11.25.0-CURRENT
