GoCentral keeps giving me an error when I add the Spreadshirt/Shop embed code. It prompts me to add the <!DOCTYPE html> identifier, but still persists with the error after I insert this. I have tried with and without the identifier and deleted and created new pages just to test.
Hi @OllyEmTV. Thanks for being part of GoDaddy Community! It sounds like the embed code from Spreadshirt isn't set up to be used within an iframe. That is how all custom coding is added when you use an HTML section in GoCentral. I would see if you can connect with Spreadshirt to see if there is a way to modify the code to work within an iframe. I hope that helps.
