By luck today, I noticed site.com/ was not redirecting to http://www.site.com/ and http://www.site.com was not adding the trailing slash as http://www.site.com. After playing around for hours with .htaccess files, pulling backup files, deleting file after file trying to figure this out, I deactivated this plugin. Right after, the redirects starting working.
While the plugin was enabled, I tried adding a 301 redirect to the .htaccess file, and all it did was broke my site. I don't think that will work.
I did see one other question on this topic with no response:
Anyone else having this issue? This can be a huge duplicate content issue. I only noticed it by mistake so others might be missing it. This, along with the wpmp_switcher duplicate content, is really alarming. I told GW to ignore the parameters but on a new page I added to my site, google indexed the page with the parameter first.
Any thoughts from the experts out there?
Has anyone tried something like this? Do a subdomain install of wordpress on say m.site.com. Then in that wordpress configuration file, point it to your main site's databases so you don't have to have multiple databases. Then point the mobile install to this sub domain. Block the subdomain from bots with a robots file. Not sure if something like that is possible?
