On a shared server you have no robots.txt for your sites, Google has always been happy, then one day Google decides it's no longer happy with any of the sites on that server, it claims it can't access the robots.txt for them. I see it expects 404 if there's no robots.txt but my server gives Error 500, according to forums that causes a problem.
Has anyone else had this type of problem, it should be easy enough to fix, but anyone know what likely caused the change? Change of settings on the shared server?
Cheers
