When you are faced with a 404 error even though you use a valid URL to an existing page, go through the following potential causes to fix the issue on your system.
Verify that the .htaccess file is present in the root of your Pagekit folder. The .htaccess file is a Apache configuration file and it's hidden on Unix-based systems; as such it may not have been unpacked. If it is not present, copy it from the Pagekit package.
It is possible as well that your web server does not allow the server's configuration to be overridden through an .htaccess file. In that case, contact your hosting provider and ask them to change the AllowOverride directive.
Another common problem is that the mod_rewrite module is not enabled on your web server, in which case you'll also have to turn to your hosting provider to have them enable this Apache module. If the module is not available, Pagekit will still work but fall back to a URL format of the form http://example.com/index.php/page/welcome.
If you are having trouble displaying pages other than the homepage of your Pagekit site. Your site might be running in a VirutalDocumentRoot.
In most cases the provided .htaccess works fine. However, if your filesystem does not match with the virtual hosting setup. You'll have to edit the RewriteBase option in the .htaccess file to match your server environment.
# Set base if your site is running in a VirtualDocumentRoot
# RewriteBase /
Uncomment the RewriteBase / option by removing the # in front of it.
If you receive a Pagekit styled error saying Error 404 then your .htaccess is functioning correctly, but your trying to reach a page that Pagekit cannot find. The most common cause of this is simply that the page has been moved or renamed.
When you are using nginx instead of Apache, make sure the server configuration for nginx is correct.
