Unable to log in. Nothing happens.
All of a sudden, I'm unable to log in to my client's site. I can get to the login page, but when I click "Log in" nothing happens, it stays on the page. It has worked fine up until yesterday. I believe I'm running the latest version of Design Extender and PowerCMS. What can I do?
Edit: this is the page I load to log in: http://buildingcongress.org/admin_cms/users_login.php
When I click "Log in" I'm directed to this page: http://buildingcongress.org/admin_cms/users_login.php?accesscheck=%2Fadmin_cms%2Findex.php%3F
I hope someone can help me soon. My client has some time-sensitive edits to make.
Thanks!
