Hi, I am facing the following issue: When trying to open the vacation or filter settings the following error is displayed: [error] FILE NOT FOUND The requested resource was not found! Please contact your server-administrator. Failed request: //servername/?_task=settings&_action=plugin.managesieve How do i fix that? I have seen that there are also skins for managesieve filters and vacation... I do not understand why this is not working. Thanks in advance! Jo
