I found out a strange but on the website which is about international local sim card solutions www.onlineabroad.com
Have a look at the footer "black block" and see how the link blocks are nicely placed within the black block.
Now put something in your shopping cart and view your shopping cart and look again. The links are now outside the black block! I have troubleshoot it for hours with no solution.
Hopefully there are some pro's here who know what is going on...
