Hi,
in my website when I try to restore the discussions of some specific user, wordpress give the error “Are you sure to do this? Retry”, what could be the reason?

This is a known bug. This might be resolved in the next release of bbPress though.

There is a workaround listed in the ticket also.

A workaround is to select the topic(s) to restore and use Bulk Action to restore.
