All seems to be working well so far. I use a number of WPSSO plugins on sites and they are great.

Not working

I tried it, I installed it, I activated it but it was doing nothing, it didn't appear on the product. it seems to me that I am downloading another plugin without which it does not work correctly, I don't understand why it is not said from the beginning that other plugins must be downloaded.

Excellent plugin
