If you enable [[plugins/filecheck]] *and* [[plugins/attachment]], then IkiWiki (e.g. via wrapper) will throw a lot of the following errors on stderr
Use of uninitialized value $size in division (/) at /.../filecheck.pm line 73.
73 is
```
sub humansize ($) {
my $size=shift;
foreach my $unit (reverse sort { $units{$a} <=> $units{$b} || $b cmp $a } keys %units) {
if ($size / $units{$unit} > 0.25) {
return (int($size / $units{$unit} * 10)/10).$unit;
}
}
return $size; # near zero, or negative
}
```
Disabling *attachment* is sufficient to stop this. *&mdash; [[Jon]] 2023-09-06*
