How to add a 404 error page?
This is something that would be done on your server.
You may have an option in your control panel that sets up different pages, if not edit your .htaccess file, and add
ErrorDocument 404 /404.html
of course you would need to set up a file called 404.html for it to reference
Thank you for your response.
My site is hosted in Boostrap, Thus no access to the server! How then within Boostrap?
Thank you, very much!
