Hi, yes i use Booking Activities – Advanced Forms and Booking Activities – Prices and Credits to set the option. I noticed that th problem is on all the product that have that type of option. The problem is not due to the others plugins, i already tested to deactivate them. When the checkbox is checked, there is an addition of the option price.
For exemple i have an other product with a +20€ option. It add 40€ when i check the “Create account” checkbox.
What is your email please to contact you, your website https://yoan-cutillas.fr/ does not work
