That makes $q a global. Bad, bad, very bad. Slap yourself on the wrist. Remove
that "use vars" line.

Now replace that with
my $q = CGI->new();

This is because Apache is using multiple processes to handle things. Sometimes
you're hitting a process for the first time, so it creates an new CGI object and
all is well. But sometimes your request goes back to a process that has already
loaded and executed this code before, so $q is not a new CGI object.
