[XServer] How to fix the broken display on the admin screen on WordPress

There are many reasons why the WordPress admin panel might display incorrectly, but I’ll introduce the method I used to fix it this time. It involves going to the server management section of Xserver and using the ‘PHP Version Switch’ to change to a different PHP version and then switch back. Doing this seems to trigger some kind of restart that restores things to normal, at least in my case.
