After submitting data from my published mobileForm (xdp) I get a error message from the browser:
"default.submit.html:1 Failed to load resource: the server responded with a status of 403 (Forbidden)"
Inside my author instance all work fine only after publishing to the publishing instance I get this error.
The problem was that the publishing server was not whitlisted on the authoring server under [adminui / settings / userManagement / configuration / settings]. After whitelisting the publishing instance for allowed references all work fine.
What is the submit action configured on the button?
Can you try enabling anonymous access and test again?
1. Go to /system/console/configMgr
2. enable anonymous access in apache sling authentication service
