Yesterday, before updating the cpanel, after I edited a package and hit ok, the next page was showing the accounts that had that package being modified. All ok.. but it never stoped. The page keept refreshing and re-sending the emails that the accounts were modified. If i don't click on a link in the menu or i don't close the whm... this keeps going on and on.
I updated the cpanel to the last stable release, the problem is still there.
