Hi,
When trying to edit using Cornerstone the page is is hanging (only see the logo pulsing). I have reviewed other threads, PHP exec time and WP memory are all in order. I have cleared caches, trying incognito, different browsers, toggling plugins, etc. This issue popped up today. My error logs show the following. We really need to get in and do updates!
