Login Issue

I have a very unusual behavior that I do not know how to remedy.

When logging in the app used to work perfectly. Now the login will fail and takes the user to this page: https://gmadmin.org/dmxConnect/api/Security/login.php.

When this is opened it renders this on the page: {“identity”:1}

Anyone have any idea how I can return to a functioning login? I believe there is a breakdown on the globals security, but I cannot figure out how to fix it.

I really need help… there’s a meeting tomorrow morning and they will need to be able to login. Ha!

Thank you for your help!
