Plugin Broke

Hello,

I installed the Plugin to our site. So when you are logged in it shows blank.

Any ideas? It works fine on my local machine.

This is the log:

PHP Fatal error: Uncaught Error: Call to a member function get_page_permastruct() on null in /var/www/web-dev-eco/wp-includes/link-template.php:357\nStack trace:\n#0 /var/www/web-dev-eco/wp-includes/link-template.php(320): _get_page_link(Object(WP_Post), false, false)\n#1 /var/www/web-dev-eco/wp-includes/link-template.php(144): get_page_link(Object(WP_Post), false, false)\n#2 /var/www/web-dev-eco/wp-content/plugins/theme-my-login/includes/class-theme-my-login.php(954): get_permalink(Object(WP_Post))\n#3 /var/www/web-dev-eco/wp-content/plugins/theme-my-login/includes/class-theme-my-login.php(690): Theme_My_Login::get_page_link(‘login’, Array)\n#4 /var/www/web-dev-eco/wp-includes/class-wp-hook.php(300): Theme_My_Login->site_url(‘https://web-dev…’, ‘wp-login.php’, ‘login’)\n#5 /var/www/web-dev-eco/wp-includes/plugin.php(203): WP_Hook->apply_filters(‘https://web-dev…’, Array)\n#6 /var/www/web-dev-eco/wp-includes/link-template.php(3088): apply_filters(‘site_url’, ‘https://web-dev…’, ‘wp-login.php’, ‘login’, NULL)\n#7 /var/www/web-dev in /var/www/web-dev-eco/wp-includes/link-template.php on line 357
