Import from vbulletin 4.2.2 doesn't work
I am trying to migrate vbulltein 4.2.2 to vanilla 2.2.1. Firstly, I want to import and convert database through the vanilla porter. On the porter site i enter all data I need to fill in. Export type is set to "All supported data", Avatars and Files are both ticked. When i click Begin Export, i get error:
Error in porter/vanilla2export.php line 1858: (8) getimagesize(): Read error!
Can you help me find out where is the problem? How can i solve it?
Thank you very much!
