I have a private xwiki and I add a public space where everyone can read.
It’s working fine except the breadcrumb deployement (and treeview deployment too). I’m stuck on “Loading…” popup message.
I don’t know which page I must allow for guest users (I try with xwiki + main space read right)
anyways, SpaceIndex macro working well.
The breadcrumb is using the Document Tree macro which is defined by XWiki.DocumentTree and XWiki.DocumentTreeMacros pages. So you probably need to give view right to these 2 pages for guest users.
