  1. I’m still not 100% sure what caused the problem, I’m guessing something in the core wordpress install was corrupted.

    I ended up installing a fresh version of wordpress, exporting and then importing my database into a new database, and uploading the media, theme, and plugins separately which seemed to do the trick.

  2. When you have a duplicate of a site on localhost or dev server and they have the same security keys it can cause a cookie collision.

    Make a change to all of the security keys in the wp-config.php file and it will reset all sessions and cookies.
