- Friendly URL. Change this option if you know that your server can support URL rewriting. If not, leave it at "No".
You may see a message such as "URL rewriting (mod_rewrite) is not active on your server or it is not possible to check your server configuration. If you want to use Friendly URLs you must activate this mod". In this case, PrestaShop cannot detect your server settings, but that does not mean the feature will not work. You must test it yourself.
- Automatically redirect to Canonical URL. Canonical URLs are a way to eliminate self-created duplicate content – which can dramatically bring your search engine rank down, as this is considered spam. To avoid search engines thinking you are spamming their index, PrestaShop uses standard
rel="canonical"link tag to indicate which is the one base URL for a given content.
While it is highly recommended to enable this option, it also depends on your theme actually implementing correctly the
<link>header tag. Ask the theme designer for more information.
- Disable apache multiviews. Apache is the most popular web server, and is most likely the be the one your web host uses for your site (although you should check this for yourself). Multiviews is a content negotiation system where the web server tries to serve the user a page in what it thinks is the best matching language version, under the same URL. Unfortunately, this might bring trouble to PrestaShop's friendly URLs. If this is the case, you can try to disable multiviews with this option.
