 * ALERT: Some of you are having trouble with the plugin when upgrading from 4.0.
   Please deactivate and activate it 2x and that generally resolves the issue. Version
   5.xx does data table rewrites and this sometimes fails during the process the
   first time. Check under your support tab and verify that your table versions 
   are 5.xx otherwise deactivate and reactivate a couple of times and you should
   be good. Email me if this doesnt resolve the issue and I will assist. [consultant@avdude.com](https://wordpress.org/support/topic/plugin-event-registration-upgrade-issues-from-version-40/consultant@avdude.com?output_format=md)
