Title: Problem with adding new post grid Last modified: June 30, 2023 --- # Problem with adding new post grid * Resolved [kamil518p](https://wordpress.org/support/users/kamil518p/) * (@kamil518p) * [2 years, 11 months ago](https://wordpress.org/support/topic/problem-with-adding-new-post-grid-2/) * I’ve just installed a Post Grid Combo on my website. I’m trying to add my first grid, but when I hit save I get the error with post_grid_recursive_sanitize_arr() function. I get the following error when I try to save: “An E_ERROR type error occurred on line 586 of the file //wp-content/plugins/post-grid/includes/ classes/class-meta-boxes.php.
