Today I had one of those rare meltdown events when I opened my wiki and there was no story river. Nada. Nothing worked.
I had installed an experimental plugin (no names) and it did something odd.
In a single-file I think it would have been hard to sort out.
On Bob (and node too, I guess) it was easy ... I simply used a file browser to see what ".tid" files were last changed and incrementally removed them. Problem solved.
Just FYI
