Hello Karol,
We are sorry to hear you are having such an issue with the dashboard page. However, we would need to understand what’s exactly the crash you described, because this could be either an application error with the browser (JavaScript) or a server error (PHP).
Our suggestion is to ensure to be using the latest version available for Vik Booking, and eventually install any missing updates. After that, we invite you to reach out to our technical support team through our website by providing additional details about your specific issue (screen shots of the browser console or of the page crashing) so that we can understand what’s causing the problem.
Unfortunately, without knowing the exact type of error, we are unable to provide support through this forum. That’s why we suggest getting in touch through our website for such a particular situation.
Thank you,
The VikWP Team
