Not Indexing Site

[Lord_Goran]

I've installed PhpDig several times on several websites all without any problems. However on this latest install, it simply isn't indexing anything.

The cron functions as it should and the results I get are as follows:
Spidering in progress...
-----------------------------
SITE : http://www.mysite.com/ (I removed my actual URL)
Exclude paths :
- @NONE@
No link in temporary table
links found : 0
...Was recently indexed
Optimizing tables...
Indexing complete !

I've tried replacing pages from sites where I have working examples only nothing seems to be working.
Safe_mode is off and magic_quotes_runtime are off and magic_quotes_gpc are on. Also allow_url_fopen is on and I've tried everything I could think of.

Any ideas?

PHP Version 4.4.7
MySQL Version 4.1.22
Apache 1.3.37

I sent out several calls for help and one of my friends suggested the following:

In the robot_functions.php page change the following from:
settype($pu['path'],'string');
settype($pu['query'],'string');
settype($pu['user'],'string');
settype($pu['pass'],'string');
settype($pu['port'],'integer');
if ($pu['port'] == 0 || $pu['port'] == 80) {
$pu['port'] = 0;
}

To this:

settype($pu['path'],'string');
settype($pu['query'],'string');
settype($pu['user'],'string');
settype($pu['pass'],'string');
settype($pu['port'],'integer');
if ($pu['port'] == '0' || $pu['port'] == '80') {
$pu['port'] = '0';
}

Wrapping the numeric values for the port with a single quote seems to have fixed the problem. It's now indexing and working just fine.
