Hi @nathanallworth
Thanks for the login info.
I can replicate the issue perfectly.
I think the issue is simply that the Divi theme is including the same timepicker JS file (which is good) but it is an older version.
Divi is including v1.4.3 and ACF includes v1.6.3.
Maybe this is causing ACF’s JS to fail?
Maybe becuase the older version doesn’t support the settings used in ACF’s JS?
If possible, can you find the line of code in the Divi theme that enqueues the timepicker JS and comment it out. Does this fix the issue?
