I install Magento about 2-3 weeks ago. I've been using it for a few months in work and decided to start a new project store with it.
Then today i went to login and my username / password appeared to be wrong. I got no errors.. just refreshed to the same login screen.
I thought it might be my password so I did the forgot email thing and got the email to reset my password and I entered a new one and it still won't let me login.
I'm using the same PC as I also do to work. What can be wrong ?
I'm using Magento 1.9.3.7
EDIT-- I just looked at the error logs and this is appearing over and over
