A moderator helped me fix another problem, and now it's time to tackle another one.
The configure button will not work for my plugins. When I click on configure for any of my plugins, it takes me to the login page and I enter my password and it brings me right back to the login page (even though I am logged in). It's an infinite loop. Yet, when I click the 'back to Tone Deaf Challenge' link in the top left, it returns me to my website and I can click the 'edit' link for any of the posts and I'm logged in. That's how I can get back to my dashboard.
Strange, right?
