Hi,

I use 1.24.2 zoneminder on ubuntu, and i have problem when i choose an Event and then i click on Video, and I get error

An error has occurred and this operation cannot continue.
For full details check your web logs for the code 'A09B7B'


SQL-ERROR(A09B7B): select E.*,M.Name as MonitorName,M.Width,M.Height,M.DefaultRate,M.DefaultScale from Events as E inner join Monitors as M on E.MonitorId = M.Id where E.Id = undefined


Any idea ?
