1)When I delete a attachment , I can't see anything in the Document Index's deleted attachment tag. The url is like "/bin/view/Main/AllDocs?view=deletedAttachments" This happens to the deleted document tag too.And when I want to rollback to previous version of a page,the deleted attachment isn't recoverd.So please tell me how to handle with this problem. 2)Some scripts doesn't work for IE,but use Firefox it can work,such as adding a user to a group. The url is like "/bin/admin/XWiki/XWikiPreferences?editor=globaladmin&section=Groups#|t=groupstable&p=1&wiki=local" It will be my pleasure to receive your early reply.Thanks.
