Thanks for your helps.The problem with my .htaccess is that,it directs all the customers to where i want them at but,all the links on the page becomes broken. Thus:
the code in my .htaccess is ./xcart/home.php
but when customers get directed to xcart/home.php
and they click any item like CD under categories, the link becomes
www.mystore.com/home.php?cat-75
instead of
www.mystore.com/XCART?home.php?cat-75.Hence an error of a non existance page.
I hope you understand what i meant.Get at me,please.Thank you.
