I encountered an error on the Apache Manager Page where it indicates that a string should be concatenated with another string, rather than a “NoneType”. Consequently, the website is displaying a 500 internal server error. Can you provide guidance on resolving this issue?
Thank you in advance.
Edit: I managed to find out what the problem was: Cyberpanel allowed me to try changing OLS reverse proxy to Apache without warning me that Apache is a paid module. I figured this out by updating Cyberpanel and accessing the Apache Manager again. This time, pricing cards showed up.
I solved the error 500 problem by deleting my website and creating another instance of with, with the backup data.
