Don't use Prestashop, piece of shit of a software.
A simple plugin to add SEO fields to Prestashop pages (with Smartblog/Betterblog support now).
Supported versions:
- 1.6.*
- Thirtybees Support (100%)
Beforehand, deactivate the option Emit SEO fields which is in Preferences -> Set up URLs so canonical and hreflang urls aren't duplicated.
Work in progress:
- Zero bugs
