• My problem is that I get validation errors after I updated to 3.1.3. The validator says that there are no such values as index or canonical or profile for rel attribute of link.

    At first, I thought that’s because of the plugin All-in-One SEO, they have an option to generate canonical URLs (deactivating the feature, clearing the cache and reloading the page a couple of times produced no better results). And then I downloaded the beta version, where I didn’t install ANY plugins but got the same validation errors.

    Does anyone have an idea how to solve my problem? I would really appreciate any help.
