Form not showing validation error on submit

Hi, just need some help regarding gravity form not showing validation error during submission. I intentionally left blank on required fields to test validation errors but the gravity form spinner won’t stop and just keep on loading without displaying any error. Please note that the form was embedded on a popup and the ajax is enable to avoid refreshing of the page.

Does anyone have an idea on what could be the cause for this issue? Any help will be appreciated. thanks.

Hi Kim. I recommend opening a support ticket for this issue:

It sounds like a theme or plugin conflict on the site.
