The main options for friendly URLs:
Friendly URL. Change this option if you know that your servercan support URL rewriting. If not, leave it at "No".
Note 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 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.

Images preferences
New in 1.5.
Image quality. You have the choice between two of the major file formats: JPEG and PNG. Both are well established among browsers. JPEG has a good compression ratio, but can result in visible artifacts. PNG's compression algorithm is not as good as JPEG's, but there are comparatively fewer visible artifacts; nonetheless, older browsers might not recognize this format.
Choosing between one or the other is often a matter of taste. That being said, JPEG remains the recommended choice. If you would rather prevent information loss because of a format change, choose the second option, "Use PNG only if the base image is in PNG format".Warning PNG format is not compatible with the "Watermark" module.
- JPEG quality. Do not choose anything below 80 or at worst 75, for fear of visible compression artifacts.
- PNG quality. Do not choose anything below 7 or at worst 6, for fear of visible compression artifacts.

This page only has two options:
Enable Shop. You can use this option to disable your shop temporarily, for instance when you need to perform maintenance on your shop.
Note The webservice will still be active, so your data will still be available to those with a key. If you want to also disable the webservice, go to the "Webservice" preference page, in the "Advanced parameters" menu.
- Maintenance IP. The maintenance IP allows people to access the shop even if it is disabled. This means that you can prevent everyone on the Internet from accessing your shop, but still allow access to the computers used by your team-members and yourself. To discover the IP address of a machine, go to http://www.whatismyip.com/ from that machine. Click "Add my IP" if you only want to add the IP of your current computer.
If you want to add more IP addresses, separate them with commas ",".
