This problem began in 2.6.5, just after I moved from one host to another. I have upgraded to 2.7, the problem continues.
My discussion settings are defaulted to allow comments, trackbacks and pings. I have my twitter plugin set to notify twitter with new posts, as well.
Every time I publish a post, making sure that checkboxes are checked, everything is set to allow comments, trackbacks, pings and twitter notify - the post publishes and disables EVERY checkbox. The post publishes "comments off" and I have to edit the post, check all the boxes, and resave.
What I'd like to know is where to begin looking to fix this. Any help would be appreciated.
