I'm working on my first project with opencart.
I activated seo friendly urls in setting. Some pages such as about-us are fine. but seo friendly urls don't work for checkout, cart, register,... pages.
For example http://onelight.ir/about-us is ok, but http://onelight.ir/register shows an 404 page and I must use the long url.
I checked my database. There's no record for register on oc_url_alias table but there's a row for about-us keyword, with value information_id=4 for query.
I checked catalog/controller/common path. There's no seo_url.php file there if that helps.
my opencart version: 2.3.0.2
Thanks a lot for your time, and sorry for my poor english.
