500 Internal Server Error

Hi. Recently my forum stopped working. Error "500 Internal Server Error". Now I restored from backup, but I would like to understand and prevent such errors in the future. Attach the error log before the forum stopped working. What was the problem?


I was able to recover the work of the forum on other hosting. But now keep getting errors. For example, when creating a new topic or in the admin. Screenshots attached. What could be the reason?

That could indicate an incomplete or corrupt restore.

Are you sure the database was viable?
Did you also restore the server files?
Are they compatible?

I think this would indicate that the files haven't been fully restored properly. I would reupload from a fresh copy downloaded from the customer area.
