Events+ and Google Maps causing white screen and errors

Hello,
I'm having several issues with the Events+ and Google Maps plugin on this site. I am getting the white screen when the Maps plugin is enabled and have a handful of error with just the events+ plugin enabled. Here are some of the errors I'm seeing:
Notice: Undefined index: custom_fields_map in /home/rezon8/public_html/pro/wp/wp-content/plugins/wpmu_dev_maps_plugin/inc/class-agm-admin-maps.php on line 550

Please help
