Banned users create error 403

Hi,

I updated the current version of iThemes security plugin on October 4th.
Since Googlebot has detected many 403 errors on my website, blocking AdWords campaigns and Robots.txt file.
After searching, I can say that the source of the problem is the functionality “Banned users”. I desabled the functionality and there is no more blocking now.

Have you made recent changes in the plugin that explains this?
Thanks in advance.

Best regards.
