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,

The detailled error message will be displayed only for admins, then when you take a screenshot of it you can disable debug mode

You will see the detailled error message at same place where you have take your screenshot in your first message

Hello,
this may be due to memory settings of your php version so maybe the php version has been changed?
read this to see if you can raise it www.itoctopus.com/allowed-memory-size-of...sted-error-on-joomla
otherwise post at tools of kunena configuration report

Hello,

@Kotsolis : it can be a query which try to get a lot of data but to investigate the issue i need the backtrace. So please enable enable debug in both Joomla! and Kunena configuration panel to have a detailled error message.

Ok so first time I got an HTTP 500 server error.

2nd time I got a blank screen and console showed this.



You can pause in 1:11 and 2:24 to see results.

Thank you.

Hello,

It could be an issue at the moment where Kunena is trying to send subscriptions for the topic and the category linked to the topic, at this time when it try to get the subscriptions it can hang.

 

Ok so you didn't tell me: How can I fix this error?
