Page not found error when changing currency

I have recently installed opencart 1.5.2.1. Pound Sterling is my default currency and my store works fine with this. I have Euro and USD also installed and enabled. When I switch to any of these currencies, I get a Page not found error. Can someone help me in fixing this issue?

link?

Hi Jay, I was able to solve the issue by disabling the custom 404 page I created. For some reason it was not working with custom 404 pages.
