XF 1.1 phpbb3 import - Server Error


Active member
two weeks ago I imported without any problems.

Now I have costumized the Xenforo a little and I want to do the final import.

In the Import Threads and Posts I get the following error:

Server Error

Jep I did, and that may be the reason. I made a few users and post to test.

I I will now try to delete the threads and users and import again.

Thanks for the extreme fast support Brogan. I really appreciate your help.

I read that great guide first time I imported - just forgot it this time..
Everything is working now - Thanks for your help.
