htaccess/permalink 404 error

Hello,

I can’t see the product and have tried the permalink fix that you suggest on your website. Still no luck. The product does show on the default permalink setting but, will not on the post name setting. Below is my htaccess file which is is correct (I think). I’ve only have one product as I’m testing Ready cart mode. The ulr is http://www.mowermedicmd.com/product/troy-built-push-mower/ with a product id of 348. any help would be greatly appreciated!

Richard
