Issue with “Salt postfix” in AIO WP Security

Hi, I installed Burst Statistic together with AIO WP Security but when I try to access the configuration page, it keeps loading and several 403 errors appear in the console.

Searching for a solution on the web I found this topic https://wordpress.org/support/topic/no-date-for-per-page-and-referrer/

By testing, I found that the problem occurs when the “Salt postfix” option is activated in AIO WP Security (in the latest version it is located in WP Security –> User Security –> Salt).

Disabling the option Burst Statistic works again.

How can I solve this?

Thanks
