It didn’t have any problems till few days ago.

Now, when I edit a post or submit a comment while I’m logged in, this page appears:
enter image description here

for example, if I send a comment while I’m logged in as an admin on my site, comment will send, but I see that page instead of comment sent page…

As you see, it shows an ((Apache CentOS , nginx)) server, but my server is a windows (IIS) server!!

is my site hacked? or …? What’s going wrong with my website?!?

The problem was from PubSubHubbub plugin. (I think from invalid sites on its settings)

I deactivated it and everything is fine now.
