Hi,
Thanks for sharing the link where you published the block/widget “Search Form” of VikBooking.
The form isn’t working, because the settings of the block/widget are invalid. In fact, if you inspect the source code of the page you linked, you will see that the form action, hence the landing page, is missing a page/post ID. This is because from the settings of the block/widget you need to select the landing page, which will have to be a working Shortcode of VikBooking previously configured.
Starting from the version 1.6.7 of VikBooking you can manage the Shortcodes either from the apposite page in the wp-admin section of VikBooking, or you can choose the related block type within Gutenberg when you create a new page/post. Once the basic shortcodes have been properly configured (Search Form, Rooms List and Booking Details should always be available on your site), you can work on the settings of the widgets/blocks, like the “Search Form” widget in the page of your website that you linked.
We hope this helps!
The VikWP Team
