Hi! I created a login just a few days ago and now it says I have the wrong password, which I don't! I even tried resetting my password and it still tells me it's wrong. Also the facebook sign up is not working.
I haven't update the login system for over a year so it is strange indeed that you are experiencing problems with the username/password login. Do you use any special characters? I tried to replicate your issue without success.
Thanks for testing the facebook login, it is indeed not working. I have now removed the social login feature until I have time to fix it.
