Error when trying to uninstall

Hi,

I have the following error when trying to uninstall i-IMSCP:

Quote

iMSCP::Stepper::_callback: Global symbol "$rs" requires explicit package name (did you forget to declare "my $rs"?) at /var/www/imscp/engine/setup/../PerlLib/Servers/httpd/apache_php_fpm/uninstaller.pm line 150, <$fh> line 12.

at imscp-uninstall line 108.

Any ideas? Thanks in advance.

OS: Ubuntu 16.04.5 LTS

i-MSCP version: 1.5.3

EDIT: for now, I just commented that block of code in uninstaller.pm:

Quote

for ( '000-default', 'default' ) {

next unless -f "$self->{'config'}->{'HTTPD_SITES_AVAILABLE_DIR'}/$_";

$rs = $self->{'httpd'}->enableSites( $_ );

return $rs if $rs;

}

and the uninstall process finished. If i am not wrong is because I do not have the default site conf files of apache2 (I always remove those files).
