All I had to do was uninstall premium theme which I was using, then re-install the same theme. That fixes it.
Thanks.
Well… as soon as I switch to it, it gives same message… when that happens the address bar shows “http://fgholylight.org/wp-admin/post.php” and no matter what kind of update you do it will show the same error message. I’ve tried to update php file without space thing, but didn’t work.
When I turn off all plugins, like 10 of them, then 10 lines of the same message appears on the browser…
Thanks.
