I was working on the backend of my WordPress site exitstrata.com and tried to visit the page to check the changes I was making. When I tried to visit the site I received the following error:
Fatal error: Call to undefined method stdClass::in_admin() in D:\Hosting\3257586\html\exitstrata\wp-includes\load.php on line 587
Unfortunately, I closed my window open to the backend of the site. Now when I try to log back in to the main site it says my username is invalid. I am using a friends username to ask this question so that I can save my site.
Very confused and don't understand what I could've done to cause this error.
Thank you for you help! It literally means the world.
