Yesterday, all the comments disappeared from my Wordpress 4.2.3 site, running Genesis framework with Foodie Pro theme.
I have tried disabling all plugins and deleting cache, checked that the right option is selected under Genesis site settings ie to allow comments on posts; also under Settings: Discussion.
I've tried another theme and it made no difference.
The comment form appears below posts, but I was unable to send a test comment - the site just refreshed to a blank page.
In the dashboard, under Comments, it reports no comments exist. Yikes! Please help me get my comments back.
