Robots.txt Blocked Most Site URLs Because of Canonical

[s_EOgi_Bear]

Had a bit of a "Gotcha" in Magento.

We had Yoast Canonical Links extension which worked well , but then we installed Mageworx SEO Suite.. which broke Canonical Links.

Unfortunately it started putting www.mysite.com/catalog/product/view/id/516/   as the Canonical Link -  and all URLs with /catalog/productview/*  is blocked in Robots.txt

So unfortunately We told Google that the correct page is also a blocked page. they haven't been removed as far as I can see but traffic has certainly dropped.

We have also , at the same time had some Site changes grouping some pages & having 301 redirects.

Resubmitted site map & did a fetch as google.

Any other ideas?  And Idea how long it will take to become unblocked?
