Have you encountered the error on your wordpress blog where your webpage shows only -1 written on some post and there is no more post generated below it?
I have experienced it before too but just experienced it today too.
Well, how to fix this issue? this time it was pretty much simple. I just went to my wordpress dashboard > posts. Unpublised the post by making it a draft and saving it and then publishing it again!
This published the post and there was no more minus one ( -1 ) error on the page!
If you are still unable to solve it, or the publish / unpublish button is not working or taking too long to process, then try repairing and optimizing your mysql database.
