Several users have reported login problems today.

Users having an active "keep me logged in" option were likely not experiencing any trouble, however those who used the login form at the front page were returning to the same page without being allowed into the system.

We have identified the cause, which is an faulty update of the page caching which ocurred yesterday at midnight.

In other words: everyone's accounts are operational as usual, but we are having a bug in the system that might be preventing you from logging in. We are working on the cause right now.

If you are affected, please stay tuned on this thread.
