changing authentication method here on ask.sagemath.org fails

edit

Since myopenid [1] is history now, I have to find a different authentication method here on ask.sagemath.org. (I logged in at the end of January, so for a short time I'm able to ask here). The problem is, that "manage login methods" on my profile gives the following error message:

Internal server error
system error log is recorded, error will be fixed as soon as possible
please report the error to the site administrators if you wish

Can someone do something against it?

PS: I sent a similar message in the middle of January via "give feedback".
