Upgraded WebCenter Sites from 12.2.1.0 directly to 12.2.1.2 (skipped 12.2.1.1)
Had initial problem of error popup stating error reading configuration file. Oracle SR identified it looks like WCS_Conversion and WCS_Event AssetTypes were supposed to be removed from Sites 12.2.1.1, so they should not exist in 12.2.1.2 either. Had to manually delete the 2 rows for the WCS_Conversion and WCS_Event AssetTypes in the AssetType table
Popup error went away, however, still getting errors with my assets such as images not rendering, etc.
I am also seeing messages such as MISSING TRANSLATION KEY when I open my assets within the contributor UI (see screenshots)
What is this error? I have never seen before and it shows up on everything. How does it get fixed?
