use the paste code option (in validator)
do not enter the address there
because that validator is blocked (all of you who use a free subdomain)
read
besides, don’t give to validator some your internal pages (urls) that does the internal work,
but only those pages that will be displayed to users.
what does the validator have to do with fetch SQL? nothing.
but ok, I don’t know your code well enough from the inside, so do what you want
