Tried to set up the first sidebar via Appearance ->Sidebars, however the following error message is displayed-
Warning: array_key_exists() expects parameter 2 to be array, boolean given in /home/…/public_html/…/wp-content/themes/x/framework/functions/global/admin/sidebars.php on line 378
Warning: Cannot modify header information - headers already sent by (output started at /home/…/public_html/…/wp-content/themes/x/framework/functions/global/admin/sidebars.php:378) in /home/…/public_html/…/wp-includes/pluggable.php on line 1210
Suggestions welcome. Thanks
