I was trying to help a client with posting on her WP blog, and something has gone very wrong. I get this message:
Fatal error: Call to a member function register_handler() on a non-object in D:\Hosting\7872449\html\wp-includes\media.php on line 1243
I think I was updating the most recent version of WP when it started hanging and then failed, and now this. Can someone help me, please?
Thanks.
