Custom error pages

Two easy steps are involved in creating your custom http error pages:

Copy error.php file to your domain's /htdocs directory.
Edit your /htdocs/.htaccess file and add the lines below.

.htaccess: # Add to .htaccess the following lines # each handling the error associated with # respected code. Find reference at # http://en.wikipedia.org/wiki/List_of_HTTP_status_codes # The most common first = not found ErrorDocument 404 /error.php?e=404 ErrorDocument 400 /error.php?e=400 ErrorDocument 401 /error.php?e=401 ErrorDocument 403 /error.php?e=403 ErrorDocument 405 /error.php?e=405 ErrorDocument 408 /error.php?e=408 ErrorDocument 410 /error.php?e=410 ErrorDocument 411 /error.php?e=411 ErrorDocument 412 /error.php?e=412 ErrorDocument 413 /error.php?e=413 ErrorDocument 414 /error.php?e=414 ErrorDocument 415 /error.php?e=415 ErrorDocument 500 /error.php?e=500 ErrorDocument 501 /error.php?e=501 ErrorDocument 502 /error.php?e=502 ErrorDocument 503 /error.php?e=503 ErrorDocument 506 /error.php?e=506
