WordPress version: 3.4.1
WordPress SEO version: 1.2.5
I did this: i installed WP SEO 1.2.5, imported data from All in One SEO, desactivated AiO SEO and activated WP SEO 1.2.5
I expected the plugin to do this: put the right canonical url in all pages
Instead it did this: for some search result pages, the canonical url go to a 404 page.
For exemple, this page http://www.dropshipping-france.fr/search/boutique+dropshipping/page/2/ has the canonical url :
http://www.dropshipping-france.fr/search/boutique%2Bdropshipping/page/2/ that give a 404 page.
It seems to be a problem with :
%2B and + in canonical urls
But it is strange because it seems to append only for some search pages and not for all...
This page http://www.dropshipping-france.fr/search/boutique+ligne/
Has a good canonical :
GWT alert me that it found a lot of 404 erros (more than 30) and all are coming from a bad canonical since i've installed the plugin.
What can i do please ?
