Hello,
Thank you for your screenshot. This problem is definitely caused by some other external plugin loading his resources inside Vik Booking admin pages. If you analyze the page with a browser inspector and select for example the “Prices and Payments” tab, you will see some CSS files loaded by some other plugin causing the conflict.
Another solution might be disabling the external plugins installed on your website one by one and seeing which one is creating this problem.
If you can not recognize which plugin is creating the problem, you can contact us by using our official website to get further technical help.
I hope this helps.
Best Regards,
VikWP Staff
