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.
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
