Interesting. I’m having a very similar issue on one of my sites. I’m not using Woocommerce though.
But I am seeing the following message in my wp-admin area with WPDEBUG set to true:
Notice: has_cap was called with an argument that is deprecated since version 2.0.0! Usage of user levels is deprecated. Use capabilities instead. in /home3/oodzopmy/public_html/gemgreyhounds/wp-includes/functions.php on line 4045
Would love to know what’s causing it as I’m getting errors when trying to activate some plugins.
