Delete DB entry on live mobile site not working

I have tested the deletion code on all forms, live and sandbox. My delete code works everywhere but the live mobile version which either hangs in a “loading” mode forever and doesn’t close the lightbox or doesn’t allow the button to be clicked at all.

Any suggestions?

Replicate: click the trash icon and then fill the form, click delete.
What should happen: the lightbox closes and the repeater refreshes with the entry gone.
