Critical After deleting a course and returning to the course management page I encountered the following error...
Notice: Undefined offset: 3 in D:\xampp\htdocs\master_integration\lib\coursecatlib.php on line 1433

Coding error detected, it must be fixed by a programmer: PHP catchable fatal error

I added a bit of debugging code around where the error was happening. It seems that there was an id for the course I had just deleted still in the cache, even though there was no longer a course record in the DB...

Purging caches removed the error.
