Description

Hi all!
I'm trying to migrate my repositories hosted on my own gitlab-ce instance to a gitea server (due to performance issues and the fact that gitlab is really bloated and appears to have a head of its own).
When creating a repo from scratch I can add and edit wiki pages just fine, however if I migrate a repo from gitlab I get a 500 error, showing the above line in the log.

Could not try on https://try.gitea.io since I didn't receive activation email for account yet.

This might be related to this gogs issue.

@tboerger maybe try.gitea.io should disable register confirm email?

[strk]

@lunny I'd keep the confirm email, at least we check if it works or not...

I think this has been fixed by #544, maybe you could use a newer version to test it.

@lunny Thanks! Tried with 1.0.1:

• Empty wikis are removed, everything works as expected
• Nonempty wikis are migrated (i.e. no "Welcome to Wiki" page), but the "Pages" page is empty

[lunny]

So that's another issue. You can change this issue's title or maybe you can fire another.

I will close this, please feel free to reopen it.
