[otrs] problem with Autoresponse <-> Queue

Hi, I have a problem with the page of "Autoresponse <-> Queue". When I click on "Change setting" I dont see the page (the menu of otrs is shown, only that section is not showed). When I forced the url I see it (for example http://xxx.yyy.zzz/otrs/index.pl?Action=AdminQueueAutoResponse&Subaction =ChangeAction&ID=21&IDs=4). The database is imported by another otrs db. I have changed nothing in the source, can be data damaged? So how can I solve this problem? thanks, Giovanni
