We are in the process of moving to Lightning, and I have been asked to test my public facing skuid pages in a sandbox before turning on Lightning in Production.
Currently, I can get the skuid page to work when I preview that page, but the live site page generates the following errors (see screen shot for more detail). I’m not sure how to modify the skuid to handle these GET requests.
GET https://partial-pmi.cs20.force.com/soap/ajax/41.0/apex.js net::ERR_ABORTED 404 (Not Found)
partial-pmi.cs20.force.com/:260 GET https://partial-pmi.cs20.force.com/soap/ajax/41.0/connection.js net::ERR_ABORTED 404 (Not Found)
