Hi,
I'm having a bizarre problem. I upgraded to WP 2.6 and then to 2.61 recently with all other settings, themes, plugins unchanged.
After every 2 days, the comments form on ALL my posts and pages turns itself off, the discussion settings are overruled and 'User must be registered and logged in before commenting' option gets enabled.
I have to manually run
UPDATE wp_posts SET comment_status = 'open';
to enable the comments form and change the commenting options but after 2 days - bang! the same problem.
The database seems to act on its own. What could be the reasons? Note that I haven't changed any plugins or themes in ages but this problem is occurring since past 2 weeks.
Help appreciated. Thanks in advance.
