Fatal error: Uncaught Error: message when adding new user to WordPress


I need to set up a new user account for a new writer for my wordpress site. When doing so and trying to log in as them I received the following message:

Fatal error: Uncaught Error: Call to a member function admin_page_url() on null in /home/customer/www/lovedbycurls.com/public_html/wp-content/plugins/optinmonster/OMAPI/Welcome.php:353 Stack trace: #0 /home/customer/www/lovedbycurls.com/public_html/wp-content/plugins/optinmonster/OMAPI/Pointer.php(85): OMAPI_Welcome->get_link() #1 /home/customer/www/lovedbycurls.com/public_html/wp-includes/class-wp-hook.php(287): OMAPI_Pointer->load_pointer('index.php') #2 /home/customer/www/lovedbycurls.com/public_html/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #3 /home/customer/www/lovedbycurls.com/public_html/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #4 /home/customer/www/lovedbycurls.com/public_html/wp-admin/admin-header.php(102): do_action('admin_enqueue_s...', 'index.php') #5 /home/customer/www/lovedbycurls.com/public_html/wp-admin/index.php(111): require_once('/home/customer/...') #6 {main} thrown in /home/customer/www/lovedbycurls.com/public_html/wp-content/plugins/optinmonster/OMAPI/Welcome.php on line 353

There has been a critical error on your website. Please check your site admin email inbox for instructions.

– I haven’t received an email in my admin email inbox so I’m not quite sure what this means.

Many thanks in advance.
