XF 1.4 Server error when batch update moving threads

[Stuart Wright]

I'm moving all the threads from one forum to another. There are 1,274 altogether.
I get this error every time:

An exception occurred: The session has been saved and is now read-only. in /home/sites/avforums/public_html/library/XenForo/Session.php on line 635

Help!
Thanks

That looks to be an issue in your AVForums/ThreadProduct add-on.

@Stuart Wright

library/AVForums/ThreadProduct/DataWriter/Discussion/Thread.php

Change:

$session->remove('avforumsThreadProd');

To:

if (!$session->saved())
{
    $session->remove('avforumsThreadProd');
}

That should certainly solve this problem; but I think other changes will need to be made. I will look at them for you this evening.

Thank you both. I will deactivate the addon temporarily for the purpose of moving the threads.
