I am trying to use GeneratePress and GP Premium with the GiveWP plugin for a nonprofit site.
When I go to create a donor form, I get the following error (with WP_DEBUG enabled):
Warning: Illegal string offset ‘_meta-generate-page-header-image’ in /www/wp-content/plugins/gp-premium/page-header/functions/metabox.php on line 22 Fatal error: Uncaught Error: Cannot use string offset as an array in /www/wp-content/plugins/gp-premium/page-header/functions/metabox.php:22 Stack trace: #0 /www/wp-includes/class-wp-hook.php(288): add_generate_page_header_meta_box(‘give_forms’) #1 /www/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #2 /www/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /www/wp-admin/edit-form-advanced.php(334): do_action(‘add_meta_boxes’, ‘give_forms’, Object(WP_Post)) #4 /www/wp-admin/post-new.php(76): include(‘/www/wp-admin/e…’) #5 {main} thrown in /www/wp-content/plugins/gp-premium/page-header/functions/metabox.php on line 22
