"View Site As" broken on front-end


I am using the Membership plugin on our site and the "View Site As" functionality does not work on the front end, it always reverts back to "Membership Admin". I updated to the latest version (which stated it fixed this issue) with no luck.

If you switch while in wp-admin, then it stays as what was switched too. I thought it might have been a caching issue, but I disabled caching with no luck. Any ideas why it doesn't work on the front?
