stuck in a theme

Login into your admin panel and go to Presentation, then from the Themes list select (on the far right) the theme you’d like to be active.

try http://yourdomain.com/wp-admin/ to get to the login screen, or if you’re already logged in, then it takes you to the admin panel.

I tend to have a short cut to the admin area in my toolbar as I don’t include a login for my theme only a logout.

if you installed in a subfolder try http://yourdomain.com/subfoldername/wp-admin
