So, the issue is with the plugin, and not on my end?
Set Debug Mode to true in the wp_config file. I get these notices:
Strict Standards: Redefining already defined constructor for class MobileSmart in /home/xxxxxxx/public_html/wp-content/plugins/mobile-smart-pro/mobile-smart-pro.php on line 146
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /home/xxxxxxx/public_html/wp-includes/functions.php on line 3193
If I remove the plugin completely, these notices disappear.
