I have just been thru an upgrade at a client to 10.6 (the previous version was 10.4).
The database and clients upgraded with no issues.
I also had to update the iBOs on their website, which is a custom web applications using the iBO com objects.
I am now recieveing multiple iBO errors, and have no idea why.

I first completed the upgrade in a test environment, with no issues, and cannot recreate the problems in test.
The entrire web application is .net and the iBOs have been updated to new version.

Any thoughts? Attached are the errors.
