Just wondering, anybody can guest the issue.

I've joomla + invitex installed, then when i attempted to produce a menu for invitex in primary menu, everthing looks fine.

However the issue is, after i clicked on around the invite menu, lead to page not found. The url for invite menu looks funny, such as this :

http://foxy.local/component/option,com_invitex/Itemid,35/view,invites/

Anybody understand how to fix?

You mean the foxy.local? In the event that looks wrong, it is a establishing your Joomla configuration.php file (the domain) or invitex configurations.
