Very good! Congrats! Would encourage you to find out all you can about set up ... where things are located, etc. and record that info in something you have locally or even in your profile here.
Sounds like you might on a system that creates error_log files in the code directory where the error occurs. Thus, might have to use cPanel's file browsing to search the entire code base for 'error_log' files. Plus any additional protects ... like mod_security or securi ... those have rules that could be triggered by legit actions in moodle code. Those added on protections also falsely report things like error 500's to hide from would be hackers.
Anyhoooo ... thanks Matteo for reminding me (again) ... and again congrats on finding resolution to your own problem!
