We've got one user that is missing the Publish box on the post edit screen. If a site admin logs into the same blog, the Publish box shows up fine so it appears to be something unique to that user/blog combination.
There might be a bug in how Subscribe2 hooks into the screen options, but we disabled that plugin and Deanna even wrote a little fix for it, but the user still isn't seeing the Publish box.
I've looked through wp_usermeta a bit but I don't see anything that jumps out. Having a bit of trouble decoding some of the cryptically obscure value strings though. (WP documentation LOL!)
Anyone seen this? Thoughts or tips on places to look?
