I have met the similar issue about updating my Wowchemy academic website. I have tried the solution from recent posts Wowchemy site stopped working. The error message I got are different to the ones mentioned in the following post
Here is my error message:
hugo v0.130.0+extended darwin/arm64 BuildDate=2024-07-29T13:51:56Z VendorInfo=brew
ERROR Failed to resolve output formats: OutputFormat with key "wowchemycms_config" not found
Anyone has met the same issue. I don’t really want to transfer everything to the new version.
Update:
Try to downgrade the hugo to the version 0.1190. It is working without any changes!
