Just refreshing a sensor page and got this display:
FormEdit/Sensor page/John Mure of Caldwell (c1515-c1554)/sensor
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 (10.8.64.69)".
Reloaded the page and no apparent problem. ("Order of Charlemagne: 26", incidentally)
