Invalid Node Id Specifed

[Stefan118]

We need access to the database through a support ticket. With the information, there is no reason to have this error. First we need to know what the invalid ID is and manually look for why it is being called in the database.

Does this also appy to my case?
Looks very simular to the problem of TS.
In some subforums normal users can post topics, in other subforums they get that invalid node id message.
Admin can post everywhere.

I tried to run the query's, but on all 3 i got the error 1064 something went wrong in the syntax.

I can create a ticket if you like...
