 * Fatal error: Call to undefined function wp_get_current_user() in /………wp-includes/
   capabilities.php on line 1203
 * I’m getting the following error after trying to upgrade Meteor Sldes on a Multisite
   setup. Can’t get into my network admin area at all which is quite crippling I
   can’t install new plugins on any network sites. Any ideas? I tried deleting the
   plugin but that changed nothing. I went into the database and deleted the settings
   info for the plugin no change…
 * Thanks

 * well, I have experienced this issue before, and this was the cause:
 * I was using “current_user_can(‘edit_posts’);”
 * The issue was I was doing this on a login_redirect hook. When you first go to
   the /wp-admin, it calls this, but you are not logged in yet. The user the function
   receives is a WP Error, rather than a WP User.
 * Do you have this function running anywhere without a check for if the $user is
   actually a user?
