I have a domain www.jsrservices.com and a subdomain www.mobile.jsrservices.com.  I created the sub domain to be more mobile friendly.  The problem is that the search function doesn't work on the sub domain, but does on the domain.  I've looked all of the information on answers and nothing seems to fit.  When it tries to search I get the error message 404 - File or directory not found".  Any help would be appreciated.
