Well-known member
It looks like you are missing authentication information. Where did you import from?

Looks like there are some custom things being involved here, possibly with custom auth schemes and/or bad dynamic extension of auth schemes.
There were several imports from XenForo 1.2.0 into a XenForo 1.2.2 installation.

Several forums were merged with accounts being merged by email or username.

Next we are also using the XenCentral add-on, could it possibly be related to it?
Yes it does have an auth system, that last night I had forgotten to put the global salt into the config, so perhaps that was it, I put one in today and maybe it fixed it. Will wait and see if issues continue to occur.
