I am trying to import a phpBB forum into vanilla. I have successfully exported phpbb with the exporter, but when I go to the importer in 2.1.3 and try to import it, as soon as I click "Start" it shows the error message:
"Something has gone wrong.
We've run into a problem and are unable to handle this request right now.
Please check back in a little while."
Any idea what's up and why it wont import?
