Support » Plugin: Ninja Forms - The Easy and Powerful Forms Builder » convert_to_screen error with WP_List_Table

  • Resolved Carsten Meiselbach



    currently I’m getting the following error.log entries when calling one of my Admin Pages when logged in within WordPress. I’m using PHP 7.0.6, WordPress latest stable build.

    [29-Jan-2017 19:16:56 UTC] PHP Fatal error: Uncaught Error: Call to undefined function convert_to_screen() in /wordpress/wp-admin/includes/class-wp-list-table.php:143
    Stack trace:

    #6 /wordpress/wp-admin/includes/screen.php(232): WP_ in /wordpress/wp-admin/includes/class-wp-list-table.php on line 143

    “convert_to_screens” seems to be quite “common”, several WordPress Plugins seems to be having problems here. Do you have any further info for to fix this?

    Kind regards & thanks for the Plugin,
