如何从URL中删除IP前缀

Trying to figure out how to remove the IP the is pre-fixed to my URL once I move off the homepage.

Tried everything - perhaps it's something simple that I'm missing. The site has recently been migrated....

Use reletive url path and add the base in head

<base href="http://www.clpromotions.co.uk/" /> 

<a href="clpromotions.co.uk/index.php/calendars">Promotional Calendars 2016</a>

Or make a constant base url and append on each link

Const BASE_URL = 'http://www.clpromotions.co.uk';

<a href="<?=BASE_URL?>/index.php/calendars">Promotional Calendars 2016</a>

Or you can start the url with domain root with /

<a href="/index.php/calendars">Promotional Calendars 2016</a>

Thanks very much.

I found the issue in config under

$config['root_path'] =

Thanks.
