XF 2.1 Members cannot post in threads


I may not explain this well but here goes.

We moved host last week to a new host server. It turns out the DNS name server change did not take. That was fixed but we had posts from only the date of the move, April 16. The forum has been re-imported to the new host and everything posted in the last week is there. All posts and changes are current.

However, now no one (even admins) can post within a thread or start a new thread.

Is there a debug feature that may have gotten turned on or off some time during the move? Is there a "post" button which has been turned off somewhere? :unsure:

You haven't clarified what errors or messages are displayed when attempting to post, but if no changes were made to the XF settings or permissions then something went wrong with the server move or database dump and restore.

You may want to do it again.


There's no error message. I just type in text, post reply, I see the little lines across the top right corner and nothing's posted.

But the dump and restore is a thought.


There were no new error messages. The last was April 9, too many connections.

Server size is no problem. We don't use cPanel now and the new server sees no problems at all.


There no new ones at the time. Now we have several pages of:

I think that the path to the DB has been changed. The site looks like it's a copy of the site at the time of the transfer but has no dynamic function. But TY Brogan, that give me a starting point. (I just woke up so my brain is not fully operational as yet,

File health check: All 4,517 checked files are present and correct.

Also get this message in email:

error: stat of /var/log/exim/processlog failed: No such file or directory

And this is new:

Error: Failed to detect code [ryo41dpPXdaKkshCXY] in SYSLOG_LOG [/var/log/messages]

This is a mess.

Oops! We ran into some problems.

We're also seeing this in the system logs now:

It seems that something in the site is causing PHP to crash before it can finish the post.


Oh, here's a new thing that popped up this morning. I sure didn't alter anything.

Check completed on 4,517 files. The files listed below have contents different from those originally downloaded.

If you have edited these files yourself, you may ignore this message, otherwise you should investigate further as this may be evidence of corrupted or altered files.
