Over a week ago we switched our site from ASP to ASP.NET, and 2 days ago I discovered that Google has not been able to index our site. In Webmaster tools both the site map XML and the googlebot are reporting site unreachable.
I checked the robot.tx and Google is able to see that, I even have it now with no disable links. When I try the fetch as googlebot, it shows unreadable. I put a html page into the fetch and it finds it fine.
I looked into my web logs and I see the 500 error happening when teh browser is the googlebot.
I found web posts about the issue with the ASP.net 2.0 Mozilla detection hole and followed those steps. Do not think that is the issues though. I loaded the plugging into FF (User Agent Switcher) and I can browse the site with no errors.
I am not sure what else I am missing or where else to check.
My site is www.planetshoes.com
Any help would be great.
