BUG: userCard.php not displaying on live site, but working on localhost.

Loading userCard.php directly (/userCard.php?prof=0&me=0) showed numerous mysqli errors;
Listed mismatched bind_result args, and improper free_result methods;

This version alters the syntax, and disables error reporting;
If this version works, it should still be revisited to check whether adjusted syntax is correct;
And to consolidate or fix the SQL queries in general;
Sync with upstream.
