Hi. Looks like it might be related to
this report. Search that webpage for "a57" (without quotes) and read from there. Also,
this may be of interest too.
If these number/letter combos are in fact chunk encoding size markers, then they may be on their own lines so try the following to remove them.
In robot_functions.php, in the phpdigGetUrl function, find:
PHP Code:
else {
$lines[] = $answer;
}
and replace with the following:
PHP Code:
else {
if (!eregi("^[a-z0-9]{1,3}[[:space:]]*$",$answer)) {
$lines[] = $answer;
}
}
