This has been causing me problems in two areas and finally found out it has something to do with redirects that the cart is writing.
Had a problem with new products not showing up in the main category: New Products Not Showing In Categories - General Questions - CS-Cart Community Forums
Also had problems when changing the main category of a product a different category: Changing Main Category Of Products = Seo Problems - SEO - CS-Cart Community Forums
I have traced this all down to the redirects now working properly. When I go into the 301 Redirects area of the admin, it shows that the old redirect should point to the right product but even if I cut an paste the old url into the address bar it is not redirecting. I have not found one that works yet in random testing. Anyone ever seen this?
Provide some examples
I'm having the same issues as described. Tho - haven't narrowed it down to redirects yet.
Okay, it ended up being an issue with with a mod that was custom developed for me where I have a short url for search terms mysite.com/shop/search-term will show results for said search term. I thought that may be the issue since it wasn't giving me a 404 page but a search results page. Techs fixed the issue and is working properly now.
