Hello Didier,

Thank you for reaching out to us.

Please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

Hello Didier,

Thank you for providing me with the admin credentials.

This is an issue due to the "Autoriser au-delà de la capacité maxi" option being enabled.

If this is disabled, your front-end customers won't be able to book appointments with Pending status above the maximum capacity.
Once the maximum capacity is reached appointment will close and the time slot will become unavailable.

Please disable this option and let me know if the issue persists.

Hello Didier,

Glad to be able to assist you.

Please reach out to us if you have any other questions.
