What's going wrong

Shop owners report that product pages load only with a trailing slash at the end of the address, while the same address without it returns a 404 error. Some reported the issue after switching from another permalink tool, and others saw it alongside caching plugins. A product link that works in one form and fails in the other causes broken shares, lost sales, and confused search engines. A small normalization service that enforces one URL form and redirects the other would give stores a predictable result without rewriting every product.
