Can someone help me through this??

Assuming you have followed the guide here:
https://docs.librenms.org/Extensions/NFSen/

What steps did you take to install nfsen itself?

Hello, I reset the installation of netflow, i follow this steps: Monitoring Netflow with NFsen and i also this one: NFSen - LibreNMS Docs. i copy this on my config.php file in my librenms: $config[‘nfsen_enable’] = 1;
$config[‘nfsen_split_char’] = ‘_’;
$config[‘nfsen_rrds’][] = ‘/var/nfsen/profiles-stat/live/’;
$config[‘nfsen_rrds’][] = ‘/var/nfsen/profiles-stat’;
$config[‘nfsen_base’][] = ‘/var/nfsen/’;
$config[‘nfsen_suffix’] = “_yourdomain_com”;

as you can see on the photo the netflow is currently collecting data now.

As you can see on the screenshot it is not enabled and i cannot see the netflow tab in here. what shud i do to see the netflow tab here?

in my $config[‘nfsen_suffix’] = “_yourdomain_com”; i change the value to my domain name.

Did this get resolved?
