VirtualHost 127.0.0.1:8080 overlaps with VirtualHost 127.0.0.1:8080

[warn] VirtualHost 127.0.0.1:8080 overlaps with VirtualHost 127.0.0.1:8080, the first has precedence, perhaps you need a NameVirtualHost directive

Apache listen only on 127.0.0.1 (Nginx front-end etc.) and host multiple subdomains in Apache

vi /etc/apache2/ports.conf

NameVirtualHost 127.0.0.1
Listen 127.0.0.1:80

Use this on vhosts

<virtualhost 127.0.0.1>
</virtualhost>

With latest dev version of 3.0, they have option for minify output. In /application/config/config.php just change it to TRUE

Show 404 error page instead "The URI you submitted has disallowed characters" error

it's really annoyed with this error page. I think show 404 error page is more clean

 Create a file named MY_URI.php in application/core/ and paste below code

Codeigniter Route Everything, except these Controllers

another Codeigniter routes, Codeigniter Route Everything, except these Controllers

There was a recent post on the codeigniter forums trying to get urls like these:
http://yoursite.com/your-slug
This problem could have been easily resolved using this route:

$route['(:any)'] = 'articles/$1';

In this route, all characters after the domain will be passed to the controller, 'article'.

However, the problem was he also had some controllers that he didn't want to use the route for. A quick fix for the route was to use a 'simple' regex using negative lookahead

$route['^(?!controller|controller|controller)\S*'] = "article/$1";
