WordPress: “post.php” is blank after publishing

Whilst I was helping out Bookninja earlier this week, I came across a strange problem in WordPress.

Every time we tried to publish a new blog post (or page), there would be a pause, then the page would go blank.

(This was on the “post.php” page)

I spent a long time trying to figure out what the issue was… even longer googling it!

Several pages into the Google results, I found the answer! Thank you Sean Deasy!

WordPress posting issue solved at last :)

It seems that Bookninja’s hijacker added a rogue URL to the notification/ping-list (http://www.newsisfree.com/RPCCloud), who knows why it was put there, but it was definitely the cause of the blank “post.php” issue!

After removing the rogue URL, everything was working fine again!
