Error while changing thread prefix

[tafreehm]

I just tried to change Thread prefix. and it shows error when I try to change thread prefix inline from message list temp.

Here is the error message:

The following error occurred:

I have a suspicion... that the first_post_id is not set for the thread. I can reproduce this error if I deliberately remove that value from the thread record. This should not happen normally except for after an import if the rebuild fails for some reason.

Try running this:

Admin CP -> Tools -> Rebuild Caches -> Rebuild Thread Information

Then try changing the prefix again.

Nope, still same error.

In that case I would like to examine the problem. Can you send me a PM with a URL and admin login to your forum, and a URL and login for phpmyadmin?

I just rebuilt the thread information myself and it fixed the error.
