Basically any site that I had running PublishPress Blocks would crash with the below fatal error when I attempted to go into the Customizer. I suspect it was because I never set any Block Permissions in the settings and there was a null value for the $advgb_blocks_user_roles array. I don’t know if you can have the plugin set a default Block Permission that can be changed via the settings to avoid the error?
Anyway, here is the error I got when I set wp_debug to true:
Fatal error: Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array, null given in /nas/content/live/sitename/wp-content/plugins/advanced-gutenberg/incl/advanced-gutenberg-main.php:2480 Stack trace: #0 /nas/content/live/sitename/wp-content/plugins/advanced-gutenberg/incl/advanced-gutenberg-main.php(2480): in_array(‘genesis-page-bu…’, NULL) #1 /nas/content/live/sitename/wp-content/plugins/advanced-gutenberg/incl/advanced-gutenberg-main.php(516): AdvancedGutenbergMain->getUserBlocksForGutenberg() #2 /nas/content/live/sitename/wp-content/plugins/advanced-gutenberg/incl/advanced-gutenberg-main.php(422): AdvancedGutenbergMain->advgbBlocksVariables(false) #3 /nas/content/live/sitename/wp-includes/class-wp-hook.php(307): AdvancedGutenbergMain->addEditorAssetsWidgets(‘widgets.php’) #4 /nas/content/live/sitename/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #5 /nas/content/live/sitename/wp-includes/plugin.php(474): WP_Hook->do_action(Array) #6 /nas/content/live/sitename/wp-includes/class-wp-customize-widgets.php(704): do_action(‘admin_enqueue_s…’, ‘widgets.php’) #7 /nas/content/live/sitename/wp-includes/class-wp-hook.php(307): WP_Customize_Widgets->enqueue_scripts(”) #8 /nas/content/live/sitename/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #9 /nas/content/live/sitename/wp-includes/plugin.php(474): WP_Hook->do_action(Array) #10 /nas/content/live/sitename/wp-admin/customize.php(123): do_action(‘customize_contr…’) #11 {main} thrown in /nas/content/live/sitename/wp-content/plugins/advanced-gutenberg/incl/advanced-gutenberg-main.php on line 2480
Hopefully that helps some.
