Can not access wp-admin

Hi,

I have just moved hosting provider and migrated my website, when the plugin is activated I can not access wp-admin properly, any links I click in the admin ribbon give errors similar to this:

Fatal error: Uncaught Error: [] operator not supported for strings in /home/arcoiri1/public_html/wp-content/plugins/events-manager/classes/em-events.php:63 Stack trace: #0 /home/arcoiri1/public_html/wp-content/plugins/events-manager/classes/em-events.php(124): EM_Events::get(Array, true) #1 /home/arcoiri1/public_html/wp-content/plugins/events-manager/admin/em-admin.php(21): EM_Events::count(Array) #2 /home/arcoiri1/public_html/wp-includes/class-wp-hook.php(298): em_admin_menu(”) #3 /home/arcoiri1/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #4 /home/arcoiri1/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #5 /home/arcoiri1/public_html/wp-admin/includes/menu.php(149): do_action(‘admin_menu’, ”) #6 /home/arcoiri1/public_html/wp-admin/menu.php(282): require_once(‘/home/arcoiri1/…’) #7 /home/arcoiri1/public_html/wp-admin/admin.php(138): require(‘/home/arcoiri1/…’) #8 /home/arcoiri1/public_html/wp-admin/index.php(10): require_once(‘/home/arcoiri1/…’) #9 {main} in /home/arcoiri1/public_html/wp-content/plugins/events-manager/classes/em-events.php on line 63

My hosting provider tells me it is events-manager and once deactivated all works as it should.

Their comment is:

I would recommend also contacting the developer of the plugin and addressing the issue with them. Hence the plugin developer would be able to provide you with the required level of assistance and if a specific setting is suggested, we would gladly apply it for you (if the hosting environment allows it).

Regards
Jay
