I received 6000+ crawler errors in my webmaster tools account. following is the one of the URL that identified as problematic URL.
Site is developed in Codeigniter. I allowed &,= characters in Codeigniter config.php. I only used query string for pagination like ?page=1
Concern 1: why google bot adds extra parameters in URL Concern 2: why it begins query string with & instead of ?
Please guide me, what to do to solve this issue?
