before giving the error another error is gegenerated, but i'm not able to read it because the script goes on and imports a few forums and stops at the error.

If an error is generated it SHOULD be contained in your error_log on the server as well, should you have logging enabled through your webhost. So by looking at the bottom of said error log you should be able to discover the last few errors on the site.

Hello Gizmo,
management just decided to start a new forum on the new server, so we don't require an import of the old data anymore.
So you can say I'm saved by the bell...
Thank you

Well, I suppose that's one way of getting around issues lol...
