Title: Multisite error Last modified: July 12, 2017 --- # Multisite error * Resolved [Sjoerd van Hout](https://wordpress.org/support/users/sjoerd-van-hout/) * (@sjoerd-van-hout) * [8 years, 9 months ago](https://wordpress.org/support/topic/multisite-error-16/) * Hi, * I’ve just left a review on your plugin. As a follow up, I’ve opened this topic. * After enabling the plugin across all sites in my multinetwork I get these error messages on the multisite master admin page: * `Fatal error: Uncaught Error: Call to a member function add_help_tab() on null in /Users/sjoerdvanhout/Documents/MAMP PRO/maindomain.dev/wp-admin/network/settings. php on line 24` * `Error: Call to a member function add_help_tab() on null in /Users/sjoerdvanhout/ Documents/MAMP PRO/maindomain.dev/wp-admin/network/settings.php on line 24` * So I have maindomain.com and I have sub.maindomain.com. After enabling the plugin on maindomain.com the network admin page stops working. * Hope you can help! Thanks in advance! - This topic was modified 8 years, 9 months ago by [Sjoerd van Hout](https://wordpress.org/support/users/sjoerd-van-hout/).
