"Please try to resubmit the form once again" errors

[eggerda]

This isn't happening a ton...but in the 2.X application logs, I am seeing things once in awhile...

2022/06/10 03:58:15 [error] [exception.CHttpException.500] [2409:4073:210b:d1ee:a7c:570d:622a:5ece] CHttpException: Please try to resubmit the form once again! in /var/www/vhosts/mydomain.com/mydomain.com/apps/frontend/controllers/ListsController.php:188

I go to the HTTP_REFERER to submit the form, and it works just fine... so just wondering why users are getting this sometimes (rarely, but several times a day...)

Anyone see this?

This happens if you try to double submit the subscription form with the same email address, at the same time, it is a prevention mechanism against double submissions which generally does not affect regular people's submissions but it catches automated ones. V1 did not have this feature. V2 is smarter.
