Hello,
Thanks for your message. We understand the situation, but if the issues you are facing take place on a page where you’re using the “Search Form” Shortcode or widget/block, then this may be caused by a conflict with a third-party plugin, because that content does not use any setTimeout JavaScript handler.
Also, the alert message you are getting may be presented by your browser to ask for a confirmation to re-submit previously posted data, usually through a form, and this is not a native behaviour of VikBooking either.
We suggest trying to disable some third-party plugins to test if the issues get fixed. Alternatively, you can get in touch with our technical assistance team through our websites, either by opening a ticket or by using the contact forms.
Thank you,
The VikWP Team
