Hello,
Thanks for your message. We understand the situation, but the “Continue” button displayed in the booking process is actually a submit button of a form, it is not a link.
This makes us believe that the cause of the issue is either an invalid configuration of the Shortcodes, hence no records assigned to a WordPress page/post ID, or a conflict with a third-party plugin that is somehow unsetting POST variables submitted through the form.
Especially if this issue suddenly started to happen, the problem must be related to a recent change of your website, because it cannot be an issue with the latest update, or the rest of our clients would have informed us already.
Since you are a Pro user, we kindly ask you to open a support ticket through our website so that our technicians can investigate more on the issue.
Thank you,
The VikWP Team
