The problem of references to the tracks.
For example, the actual address of the page looks like - http://demo.corejoomla.com/gps-tools/
But the same page is opened on the links of the form http://demo.corejoomla.com/gps-tools/gps-tools/gps-tools/
http://demo.corejoomla.com/gps-tools/gps-tools/gps-tools/gps-tools/gps-tools/
http://demo.corejoomla.com/gps-tools/gps-tools/gps-tools/gps-tools/gps-tools/132123/dfgdf

Another real page address - http://demo.corejoomla.com/gps-tools/viewtrack/111-under-the-sea.html
Opens on the links -
http://demo.corejoomla.com/gps-tools/viewtrack/111-und
http://demo.corejoomla.com/gps-tools/viewtrack/111-under-the-sea

It seems to me that this is not normal.
You can fix this problem?
