I copy/pasted the shortcode from the old website into the new one, but when I preview the page I get following message : Not Found The requested URL /book-online/ was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
looks like whole page is missing or link is not working. Can you please try to go to that page in WP Admin > Pages section and from there to follow the link?
Could you clarify plse? I don’t understand.
Thank you so much for a bit more explanation
Can you please paste whole link to that page so I can check it?
