But it seems that you’ve already applied the patch by removing “return”.
Now, could you tell us the shortcode you are using in “ISCRIVITI SUBITO AL CORSO DI Analisi della Lingua” section.
Hello,
We are sorry for the delay.
Here is a patch fix that will fix it. Remove the “return;” value in the code.

Are you planning to make the old website available to the public as well as the new one?
To remove the red border please use this CSS code:
.ajde_evcal_calendar.color #evcal_list .eventon_list_event p a.desc_trig:focus{box-shadow:none!important;}

We are glad your issue is resolved, if you have any further questions or concerns please create a new ticket.
The page I am referring to:

Instead of Elementor’s Checkout, could you try using WooCommerce’s default shortcode:
[woocommerce_checkout]
Perfect! Please wait for the next version. It’ll be available ASAP.
Could you also tell us your verson of EventON is from our website or CodeCanyon?
