I started this thread in the Joomla Forum based on the Google messages about resources being blocked on my site. http://forum.joomla.org/viewtopic
Turns out Google wants to have the files in some of the default Joomla robots file that are blocked, allowed. So my question is how difficult would it be to make a extension or have your sitemap extension have some automated method to do this. Kind of like your add sitemap to robots file option.
The problem with doing it manually is figuring out all the files that need to be allowed and constantly updating the robots file. Just a thought.
Might be a nice paid extension for someone to present. Google is really off their rocker on this one. Threatening ranking penalties.
