Including code from subdomain problem

[GCDR0812]

I have installed Jumi on site www.tickhillrunningclub.org
I have used the plugin to call a php file located in /modules/mod_calendar/calendarlist.php
I have created a link on the top menu of the site to the article called 'events diary'.

When this button is clicked it does render the php file, but it tries to load the top modules from a subdomain that I have www.hawsons-it.co.uk, as you can see by visiting http://www.tickhillrunningclub.org/inde ... &Itemid=59
It also displays the menu in the left position instead of user3(top).
The menu being on the left is a setting from the subdomain also

I am confused as to why this is happening???
