Hi I migrate to xwiki 1.1M3 from 1.1M2 but my access right doesn't work anymore for Space rihts. By example: In global rights: XwikiGuest allow to Edit-register and view In SandBox space XwikiGuest allot to Edit-register, view, DELETE and programming I delete and re-apply XwikiGuest rights but XWikiGuest can't delete a SandBox space. All my spaces specific access rights doesn't work anymore! Any helps? thxs PS: I try to migrate down to 1.1M2 but it doesn't work.
