Perplexed. I was editing something yesterday that the site tree will not now show me me (ie clicking on the '+' node does not reveal the children of that item).
Other users can still see the children (no security changes have been made and I am admin).
Further into that tree, there is a node that _no-one_ can expand. It simply says 'loading' forever.....
I've tried a dbflush in desperation rather than in hope. No change, although it did say some tables were repaired.
