I have been unable to login since the upgrade. When I try to login using facebook or google buttons, it just redirects me to a page that says Server Error (500). Is anyone else getting this issue? I have made a new account using the twitter button which seems to work to post this.
I have the same problem (reported elsewhere in the forums) with my firstname.lastname@example.org account. I have another account which works fine.
I’ll ping @anoek and add this to the internal priority list
This problem duplicates Can't log in, 500 Server Error although in my case I have another possible solution.
