Hi @red001,
It could be possible that the iThemes Version Management is enabled. See this article for more information about iThemes Version Management.

Also if you want to check if your site isn’t compromised, I would suggest that you download the same version of the iThemes plugin from iThemes itself and compare it with the files that were changed.
I hope this would help you out.
Step 1
Exactly what @kowbenchworks says:
Open your wp-config.php file in a text editor and remove the following 2 lines:
define(‘FORCE_SSL_LOGIN’, true);
define(‘FORCE_SSL_ADMIN’, true);
Step 2
Clear your browser cookies and data cache.
* For example the url to do so in Google Chrome
chrome://settings/clearBrowserData
Hopefully this would help everybody out.
