I just upgraded to the newest version of WordPress and all seemed to go well. But when I hit "publish" or "save" or even "save and continue editing" I always get the following error message:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST http://hyip-informer.com/blog/wp-admin/post.php.
The posts DO post though. I just have to hit "back" and then "view site" and everything looks fine from there. I just don't understand why the error message.
Reason: Error reading from remote server'
I don't believe this to be a specific version error. I got the same error prior to the upgrade.
Does anyone have any idea what causes this and what the fix could be?
Thanks in advance.
