Here's a perplexing message received when I try to create a sensor page:
A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
(SQL query hidden)
from within function "SMW::getQueryResult". Database returned error "1146: Table 'smw+genealogy.t2' doesn't exist (10.8.64.133)".

Description of issue:
Database error message. Repeated when I backtracked and tried again to create a "sensor page" in the same way as I have done hundreds of times before.
The URL I quoted was probably not quite accurate because I think I had just hit the Publish button, at which stage there's a more complex URL (which staff can read on the screenshot; it starts with "... Special:FormEdit...") - but that was the only one apparent when I backtracked to give them the URL. Anyway, when I returned to the page it had been created.
Maybe this forum will help the next person who gets such an error message: "If at first you don't succeed, ..."; "third time lucky"?
