When I enable prepend product permalinks with base page (in my case, shop), my products all throw 404's, even though they show the correct URLs.
I have prepend product permalinks with category. Before I enable prepend with base page, the working urls look like:
/product/category/product-name
Once I enable it, the urls look like
/shop/category/product-name
which is what it should be. But show's 404's whenever I try to access it.
I though it might be a server conf, but the fact that all other permalinks work, suggests that it isn't a server conf, but just in case.
I use:
Ubuntu 12.10
Nginx
Php-FPM via unix sock with APC
