OK, that leaves us with 2 options: fatal error in our code or some other plugin messing with UCP. Let’s find out which it is:
Open UCP settings (that don’t work), right-click anywhere and choose “view page source”. If it’s a fatal PHP error the source will be abruptly cut at some point and you’ll see a PHP error message – please copy/paste it.
If you don’t see anything like that and source ends with </body> and </html> then we have a CSS/JS error. Go back to the problematic page, open console (F12), go to the console tab, reload the page and there should be some red errors. Please take a screenshot or copy-paste.
