I've done a few upgrades from 4.5.4 up to 4.9.0.  I would edit my sql parameters/connection and objectdata like always.  Now I get the error message at the end of this post when I try to edit text or post appointment to calendar.  I can follow basic steps which is how I can do the dnn upgrades but sadly have little clue how to troubleshoot.  Part of me is tempted to blow away website and have my dnn hoster just install fresh copy of 5.0.0 as I want to do skin change also.  Before I do tho, is there anything basic I should check to resolve this error?  THanks.

Events is currently 04.00.02

All my events are expired so I have nothing (little) to lose by uninstalling events and reinstalling.  I know I saw the last line in event upgrade saying that it completed successfully but it's possible I missed a warning somewhere (hey, anything is possible I figure) so any reason I shouldn't uninstall and reinstall the events module?  I am able to edit text in text boxes (outside of events) so I want to say problem is just within events configuration.  Of course, thank you for your previous reply.

thanks you reinstalling events 04.00.02 fixed the error.  thanks again.
