after updating your site builder, my event display with tab section shows funny.
I have used FooEvent support and they said that they will never touch the styling of the page and got following reply from FooEvent by WooCommerce.
FooEvents does not change any tab styling and just uses the tabs as outputted by WooCommerce. This looks like your theme is not catering for them. Please contact your theme developers support to ask for assistance.
you see that tab section squashed and title of the tab display as Event Details as at the side instead of the tab label.
With regards, J
