How to Create Custom Error Documents on Plesk 10 Linux

Please add this code to your .htaccess file in the httpdocs directory.

ErrorDocument 403 /403.shtml
ErrorDocument 404 /404.shtml
ErrorDocument 500 /500.shtml

Next create a file named 403.shtml in your httpdocs folder. Now the 403 errors will yield the 403.shtml page. Repeat for 404.shtml and 500.shtml.

You can even use existing pages as the resulting page. Say you don't want any visitors seeing 404 errors on your site. You can make your home page the result, like so:

ErrorDocument 404 /index.html

If Internet Explorer is not displaying the custom error page, it is likely because the error page must be larger than 1 kilobyte.

There are many error pages which may be defined.
