Hi Keith,
This is a bit strange! Can you tell me how this profile page is being generated? Is it coming from your theme or another plugin, or is it a standard page that you created in the Pages section of your Dashboard?
Please also try running through these steps to see if there are any issues between Event Tickets Plus and something else on your site? If you don’t have a testing site already, the WP Staging plugin will let you create a quick copy of your live site that you can use for testing.
Let me know what you find.
Thanks,
Jennifer
