Hello,
Thank you for the details.

I checked the issue and found that the calendar is trying to load data through the standard WordPress AJAX endpoint: /wp-admin/admin-ajax.php

However, this request currently returns a 404 Not Found error on your website. This means that the request is not reaching WordPress/Booking Calendar correctly. In normal WordPress behavior, admin-ajax.php should be available because it is used by many WordPress plugins for dynamic front-end functionality.

This issue is usually caused by a server, firewall, security plugin, CDN, or hosting rule that blocks or hides access to /wp-admin/admin-ajax.php.

Please ask your hosting provider or website administrator to check why this URL returns 404: https://raquelpatro.com.br/wp-admin/admin-ajax.php

Also, please check whether any security plugin, firewall, Cloudflare rule, “hide wp-admin” feature, or ModSecurity rule is blocking POST requests to this file.

In WP Rocket, excluding only the page from cache may not be enough if the AJAX endpoint itself is blocked. The important point is that POST requests to /wp-admin/admin-ajax.php must be allowed.

After this endpoint is accessible again, the Booking Calendar month loading should work correctly.
Kind Regards.

If the conditions depend on the selection of options in another fields (select-boxes, checkboxes, etc..), then unfortunately, it is not possible in the Booking Calendar versions. Sorry. Some life hacks possible to check here about such similar configuration: https://wpbookingcalendar.com/faq/show-hide-fields-depend-from-selected-option/ Also check this about how to add JavaScript in the new Booking form Builder (because previous FAQ related to the legacy booking form configuration): https://wpbookingcalendar.com/faq/add-custom-javascript-booking-form-builder/

If the condition depends from the selected date in calendar, then check more here: https://wpbookingcalendar.com/faq/different-content-for-different-days-selection/

As I mentioned in my previous comment, this forum is only about the support of the Booking Calendar Free version. If you will have any other question regarding your pro version, please contact support via link that provided in the previous comment. Unfortunately, we can not provide support of paid version here, due to restriction of rules on this forum. Thank you, for understanding.

Kind Regards.

Unfortunately, currently it is not possible to configure different time slots for the different weekdays in the Free version. But we will check possibility to add this feature in the next updates.

Kind Regards.

Great. Thank you, for let us know.

Hello.

It is not possible to select and book multiple separate time slots.

However, you can use the start time and duration time or end time settings to book several consecutive hours at once.

You can find more information regarding this on the following page: https://wpbookingcalendar.com/faq/select-multiple-times/

Kind Regards.

Hello,

The reason for this issue is related to how the booking duration overlaps with the next day.

When a service is selected, such as “Truck & Trailer Washing” with a duration of 2 hours and 30 minutes, and the start time is set to 23:00 on a specific date (e.g., 2026-03-10), the end time falls at 01:30 on the following day (2026-03-11). Because only one date is selected in the calendar, the system cannot process a booking that concludes on a different day. Currently, bookings that span two different dates require the selection of both dates.

We have added an improvement for this behavior to our development roadmap for future updates. While we cannot provide a specific timeline for implementation at this moment, we appreciate you bringing this to our attention.

Kind Regards,

Hello.

You can use this simple shortcode:

[booking resource_id=1]

But please rechecked these 2 points from my previous comment:

1. Please check your actual timezone of website on the WP Booking Calendar > Settings > Admin Panel > Date and Time Formats page. You can define the timezones for your website on the WordPress > Settings General page.

2. Please note, that sometimes some other plugins or theme can override the time-zone, and define it programmatically. Probably it’s because of conflict with some other plugin or actual theme. Please try to deactivate one by one all your active plugins at the WordPress > Plugins menu and make testing after each plugin deactivation. If it does not help, please deactivate all your plugins and activate the default WordPress theme. And then retest it again.
