Need to click twice to sumbit the form

Where can we see the website in question?

Hi,

Here is the LINK,

You need to fill your email address then it will send comfirmation to your email, click on confirm and it will lead to the form you need.

What other plugins and theme do you use on the site?

Here is the SCREENSHOT of installed plugins

Which one is the theme?

Bridge theme

Try switching to the default theme and deactivating all plugins excluding Contact Form 7, Classic Editor, Wordfence Security, and Yoast SEO.

Why you are advised to deactivate plugins and switch to the default theme.

I’ve done as you said and form worked, what can I do?
I have several forms made by CF7 but only this one is not working, others work fine.
Please, advice a solution.
