Hi Radu, I did both, bulk edited/comments – allow/update, and also confirmed individual posts had the allow comments checkbox checked. Still have the same issue, any attempt to add comments to a post/blog returns a “Sorry, comments are closed for this item” message.
These are the plugins I have active:
bbPress
BuddyPress
BuddyPress Cover Photo
BuddyPress Group Email Subscription
BuddyPress Sitewide Activity Widget
Captcha Pro
Google XML Sitemaps
Jetpack
K Elements
MailChimp for WordPress
rtMedia
Slider Revolution
WPBakery Visual Composer
Thanks!
