hamed126 you can try restoring a backup to before the error occurred or you can submit a support ticket and support can take a look at whats causing it
Can we do a class/community support ticket with 100 names to get their attention faster than a few days? LOL
I don't think the problem is isolated but would love to be wrong.
PS Already tried the backup trick on one server, no difference. Will try again and any other tricks I haven't heard of before.
