I am unable to login to the backend of my Joomla site. The login form appears, but after entering a username and password it goes to a blank page ([url removed, login to view]), with nothing in the source code. It does this no matter what username/password I enter. The problem is very recent although I can't remember any changes to the backend that may have caused this.
In order to work on the site you will need to connect to my computer through TeamViewer.
Please let me know if there are any questions.
