Recently I was trying to install a test install on my server but when I try to upload the database I get the following error, If anyone is good with this sort of thing it may save me some time.
The only noteworthy thing that I can think of is that my host has updated phpmyadmin.
Just having a look at the particular table, To me it looks like that when I deleted some XF generated pages that the nodes children references did not get deleted...... Could this be correct ? (I hope not)
It's possible there were server related issues during the import, but other than that I can't suggest why it would suddenly work after failing a few times.
