I changed a bit of code in my bbpress.php file, it didn't work, so I changed everything back and then my whole site crashed. I had copied the original bbpress.php and when I changed it back I copy and pasted the original back in, so it's exactly the way it was. However when I tried to save the newly pasted code the admin panel crashed and the site crashed with this fatal error shown below. I can't access any admin settings or look at the files through the admin panel.
'Fatal Error -
<b>Fatal error</b>: Call to member function get() on a non-object in ,b./home/content/49/8492949/html/wordpress/wp-includes/query.php</b> on line <b>27</b>
Please help. I can't do anything to my site right now and it is down. Thank you!
