Answer 1

"/home/thecodin/public_html/memberlist.php on line 114"

line 114 - $MemberListEach['Group']; /* this is array use... */ $MemberListEach['Group']; /* this is array use... */

try dumping object with var_dump

Answer 2

Problem Solved.

I just had to change the return to a string insted of an array in the PDOException like Loz Cherone said.

I hope i'm done this right.
