The ErrorDocument
directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot
. In your case, this means that the actual path to the ErrorDocument
is
ErrorDocument 404 /JinPortfolio/error/404page.html
When you corrected it in your second try, the reason you see that page instead is because http://localhost/error/404page.html
doesn’t exist, hence the bit about there being a 404 error in locating the error handling document.
