XF 1.4 Unable to Post


Well-known member
So the issue has seemingly worked itself out however I'd like to try and figure out what caused the issue in the first place so i can prevent it from happening.

I jumped on my forum to check on things and I get a super long group PM from one of my users stating they were unable to post. This was happening to all my users...I got the PM 5 hours later and the problem had worked itself out somehow.

I get on FB to see a message that more or less told me the Issue had been going on since at least 11 PM est or 9 hours or so without me realizing it. Which bugs me.

The issues they reported

1. Anytime they posted it would say "A Server Error Occurred. Please try again."

2.

I am unsure what Waindigo's thing was doing wrong as it has been installed for awhile with no issue nor had i installed anything else.......

I logged into ACP and it was saying something about the Search index crashed(idk what that is) and needs to be repaired.

Any help would be welcomed!

Yes, as when posts are created the search index is updated.
Here i was thinking it was a host/server error thing. I even reached out and contacted them to see what the issue was and why my users were unable to post for the last 9 hours.


How often should we rebuild search index on our sites? It seemed so odd that the error randomly happened.

It should never need rebuilding under normal circumstances.

Crashed tables are indicative of server issues, typically MySQL restarting unexpectedly.
