However, as Safari on the iPad doesn’t provide “developer tools”, it was nearly impossible to determine what went wrong. The pages were working fine on other devices, including a normal laptop and an Android phone. Also Chrome’s emulation mode did not show any problems.

Digging into the Settings on the iPad, I found the “Web Inspector” option in the Advanced Settings tab for Safari.

I now have to use:

Oh well…
