Upgrade from 10.6.1 to 10.9.1 failure

1

Hi

I attempted to upgrade from version 10.6.1 to 10.9.1. After the upgrade, all users were unable to see any channels upon logging in.
I rolled back to version 10.6.1 without reverting the database, but users still couldn’t see any channels.
The issue was only resolved after I deleted the bannerinfo column from the channels table.

May I ask if anyone knows how to resolve this issue?
