I have installed the json module, filled in everything what needed.
After completing everything i get the message on my homepage(in the left top corner) No template found for Json module.
Did i do something wrong?
It looks like the build did not have the template. I just published a new release. You can either add the jsonmodule.tpl file to the module manually, or you can update the module with this version, https://store.thirtybees.com/shop-modules/front-office/json-module
thank you @lesley this fixed it.
