Warning: array_key_exists() expects parameter 2 to be array, bool given in /wp-content/plugins/woocommerce/includes/ admin/helper/class-wc-helper-options.php on line 54 * I’ve disabled every plugin and re-enabled them one at a time to see if another plugin was causing it but it didnt go away no matter what plugins were turned off. * Under woocommerce tools I cleared transients. * Here is the
