Ranks not displaying in post

Hi

There has been couple of problems on my forum today.

Some members ranks display in their profile but not in their posts.

Before signing in today there were no posts showing down the right side of the home page.

Then member complained she was getting a message when posting and would not allow her to post. This is what she said On certain members pages when i go to post its not working as usual but coming up with postdat on this page..click repost or cancel to avoid duplicating the transaction.

Thank you maggie
