Welp, I’m a retard. The 3.8 update overwrote the functions.php file that had my written is_tree() function .
To clarify, when I disable all plugins except widget-logic, I get this error on any page:
Fatal error: Call to undefined function is_tree() in C:\htdocs\wordpress\wp-content\plugins\widget-logic\widget_logic.php(284) : eval()’d code on line 1
I too am experiencing WSOD after upgrade to WP 3.8. I’ve tried using older versions of widget logic as far back as 0.54 but still WSOD
