* Hi, i have installed the plugin premium SEO and works well. I also installed
squirly to use some great features my other plugin doesnt have.
* All the features in the post edit page works like a charm.
* But apparently all the SEO settings doesnt have any effect in my meta code. I
activated json data, for example, and i cant see any new lines in my code. Why
the plugin isnt able to edit my code?
* I cant see either the canonical links, the href lang, dublincore, etc

* Hey,
* Thanks for your feedback. You probably have a cache plugin that doesn’t refresh
the data for your home page.
* Try to purge the cache and try again.
* Please send me the link to your blog and I will check it for you.
* Best regards,
Calin
