Ok, I get what happened.
I was changing the “Number of dates to choose” in settings but I had to change it also in every Custom Delivery Settings.
Thanks for your patient!
Hello again,
I found out the problem.
There was an incompatibility with a plugin named: Contact Form 7 – Success Page Redirects
I just deactivated it and it worked perfectly.
Thanks a lot
I am sorry, the link had a mistake. This is the url: https://grupocor.es/audiocor/test-auditivo/
And you are right something is happening with Javascript.
It must be a conflict with other plugin but I am not seeing an error in the inspector. And that’s pretty weird.
Do you know a list of plugins that may cause conflict so I can check them?
Thx a lot
