Comment (by westonruter):

 The errors that is being raised is this:

 > Deprecated: Non-static method WP_Widget_Text::form() should not be
 called statically, assuming $this from incompatible context in /app/public
 /wp-content/plugins/simple-access-control/simple-access-control.php on
 line 440
 >
 > Fatal error: Call to undefined method
 Logggedin_Widget_Text::is_legacy_instance() in /app/public/wp-
 includes/widgets/class-wp-widget-text.php on line 351

 The problem is that the plugin is not properly extending the widget. I can
 provide a patched version for you.
