Solved 500 Internal Server error after posting

I have Kunena v.5.2.14 . While I didn't do any upgrades, for 2 months now I receive a "500 Internal server error after writing a post and clicking Submit.

After that, the post is normally visible. It is just that I get the error.



Have anyone else experienced the same problem with that version?

If not it could be a MySQL tables issue? And if yes then how do I do a safe repair to the databases without ending up having serious issues?

Thank you.

Please enable the debug mode in the Kunena configuration ("General" tab), then there will be a more accurate error message.

The debug mode will show the code only for me or for all users?

Also where shall I see this code? In the backend or in the frontend?

Hello,
this may be due to memory settings of your php version so maybe the php version has been changed?
