Hi Oliver,

Delfos problem was caused by his site not having finished previous DNN upgrades, which then caused module upgrades not to occur. I'm not saying this will be the same for every instance of this error, but certainly one to look out for.

The upgrade to Events 4.1.x is a MAJOR update to the module, and makes fundamental changes to the tables. The error is caused by those changes not being completed. I have made the update non-destructive to the data, but it can leave the module unusable. I have also added coding over the last week to allow for a re-start if the upgrade times out, which it could do if there are my events on the Host.

So, if people see this error, please get in touch, and we should be able to identify the cause, and if there are still bugs, get it fixed. Make sure however, that you have a BACKUP before you upgrade. I do not intend to guide people through a manual upgrade of the data if the upgrade goes wrong, it is far too complex.

Cheers
Roger

Hi Oliver,

The upgrade error wasn't an error within the Events module in Delfo's case. I would suspect that if you have autoupgrade=false you can have the same problem with your site. To identify:-

• Have a look at the Versions table. If the lasted version (shown as three columns) is not the same as the version shown in Host Settings, then your DNN upgrades have not completed.
• Have a look in the EventQueue table. If you have items showing with IsColumn=false, then module upgrades aren't running. Yes it runs the file installs, and SQLDataProvider, but it is not running the iUpgradeable processing, which is needed for the 4.1.0 Events upgrade.
• I also noted that when you restart the application (web.config update, app Re-start Application in Host Settings) then no Application Start is logged in the event log - another symptom.

What is going on here is:-

• When AutoUpgrade is false, and the DB version is different to the app version, the Application Start event is not triggered, and the Under Construction page is displayed.
• Since no Application Start event is triggered, the EventQueue processing isn't run
• Since EventQueue processing isn't run, iUpgradeable isn't run
• Since iUpgradeable isn't run, the module fails to upgrade completely

I think when AutoUpgrade is set to false, you have to finish the DNN upgrade by accessing a specific url (I forget which). Of course you may be in a different situation, but it sounds similar.
