Hi, I’m hitting a very similar issue on anything past version 2.0, I reverted back to 1.1.0 and all is safe. On 2.0 or later if I check a box to hide for a post that say loads on my home page and I want it hidden I also get the fatal error. “Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given in ———\wp-content\plugins\wp-post-hide\includes\classes\class-xswphp-init.php:393 Stack trace: 0 ———\wp-content\plugins\wp-post-hide\includes\classes\class-xswphp-init.php(393): array_merge(NULL, Array, Array, Array) 1 ———\wp-includes\class-wp-hook.php(324): XSWPHP_Init->xswphp_hidden_posts_pages(Object(WP_Query)) 2 ———\wp-includes\class-wp-hook.php(348): WP_Hook->apply_filters(Object(WP_Query), Array) 3 ———\wp-includes\plugin.php(565): WP_Hook->do_action(Array) 4 ———\wp-includes\class-wp-query.php(1881): do_action_ref_array(‘pre_get_posts’, Array) 5 ———\wp-includes\class-wp-query.php(3852): WP_Query->get_posts() 6 C:———\”
