Thanks Pagla,

We have quiet a few MODs. Which have never caused problems before.

The line 447 is after :

# This adds one to the total of each category above the current category.
# We have to caluclate the affect of the link on each alt category as well as the main.
foreach $cat ($category, @alt_categories) {


The lines around this are :


# Add the link to the list of new links if it is new.
push (@{$new_links{$category}}, @values) if ($values[$db_isnew] eq "Yes");

# Add the link to the list of cool links if it is popular.
push (@{$cool_links{$category}}, @values) if ($values[$db_ispop] eq "Yes");

# This adds one to the total of each category above the current category.
# We have to caluclate the affect of the link on each alt category as well as the main.
foreach $cat ($category, @alt_categories) {

# Calculate the stats: the number of links and the newest link.
@categorylist = split (/\//, $cat);
$depth = $#categorylist;

# This adds one to the total of each category above the current category,
# and also marks any above categories new, if this link is new.
for $i (0 .. $depth) {
$stats{$cat}[0]++;
if ((!$stats{$cat}[1]) || &compare_dates($values[$db_modified], $stats{$cat}[1])) {
$stats{$cat}[1] = $values[$db_modified];
}
pop (@categorylist);
$cat = join("/", @categorylist);
}
}
}
close DB;


I think this was from the category MOD, so we can have sub categories. Any ideas. Any help is really appreciated.
