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.

Any ideas?

Turns out to be a memory allocation issue. I didn't implement the fix so I can't pinpoint this exactly, but I guess it's the same ballpark of things as with other threads asking about 'Files and Folders' not visible/working.
