I'm seeing a number of errors in my Google Webmasters account. The robots seem to get lost in download?version= with versions that don't exist. The result being 403 errors in Webmasters.
I am gonna tag onto this topic. I am getting the same errors from my webmaster tools -- lots of 403 errors for the download option of the Resource Manager. On my site you have to be registered to download. My robots.txt is basically the same as XenFORO. I could sure use some advice. Currently have over 1000 resources on my site and it grows daily.
