You have URE older version 4.32 installed at dev. site. There were 3 updates for version 4.32 before the latest version 4.33.

Demo can not access wp-admin even with URE deactivated. So the issue does not depend from URE Pro I suppose. It’s related to some other plugin. You can deactivate all plugins – retest login and then re-activate plugins one by one to isolation a source of this conflict.
