Yahoo has withdrawn YQL from service. It's the backend tool used by those widgets to work with Zazzle RSS feeds. Alternatives are being looked into.
This is what they say.
Important EOL Notice: As of Thursday, Jan. 3, 2019, the YQL service at query.yahooapis.com will be retired. This will impact users of datatables.org as well as developers who creates features using this YQL service.
To continue using our free Yahoo Weather APIs, use https://weather-ydn-yql.media.yahoo.com/forecastrss as your new API endpoint. Contact yahoo-weather-ydn-api@oath.com for credentials to onboard to this free Yahoo Weather API service. Other YQL based services that use query.yahooapis.com will no longer operate.
All Society6 tools are broken as well. Luckily I'd already removed the dependency on YQL from all but those two Zazzle widgets but hadn't even started on the Society6 Nifty tools.
Watch this space for any developments.
