I've read the other related topics and none of the solutions have worked.
I have a brand new wordpress install using the default theme. I can write posts, but when I delete one and navigate away from the "Manage > Posts" page, upon returning, the post is back.
The same goes for comments. I can't delete those either. It looks like I delete them, but when I navigate away and return, they are back.
Thanks in advance for any help.
