Thanks for the report.
Code:https://api.mania-exchange.com/{site}/tracks/list/latest
This is deprecated now, according to our
API Documentation.
Instead, you must use each sites' search API directly by visiting the specified URL.
Code:https://{site}.mania-exchange.com/tracksearch2/search?api=on&format={format}&{params}
More info about that in the
API Documentation, including all the
enumeration values.
In short, we changed things at some point and UASECO hasn't been updated to work with the new way.
The plugin developer for UASECO would have to update their plugin to work with the current API.
