Custom Plugin Creation Question

So i've been following the API on creating a custom plugin with amember pretty easy, i've got a grasp on the callback actions and started writing code to fit... I ran into a bit of a snag (sorta) that I was able to bypass but I am curious how/what/why this occurs?

There is an error that is causing the plugin to exit prematurely. It errors:
"Error. Please configure 'plugin_template' plugin at aMember CP -> Setup -> plugin_template" this even shows up in a session dump.

I can bypass this by commenting out sections (below) of this 'check' function and everything runs as expected. what exactly is it looking for? I don't have any config variables, so no setup just SQL queries. Am I ok bypassing this (seemingly)?

It may be something I missed, I combed the documentation but its sparing in that department and not much here in the forum either. Hope this may help someone else too.

Basically what is this function?

Code:

function check_setup_plugin_template(){
    global $plugin_config, $config, $db;
    
    $this_config = $plugin_config['protect']['plugin_template'];
    $nuke_db = $this_config['db'];
    if (!$nuke_db) {
        $error = "Error. Please configure 'plugin_template' plugin at aMember CP -> Setup -> plugin_template";
        if (!$_SESSION['check_setup_plugin_template_error']) $db->log_error ($error);
        $_SESSION['check_setup_plugin_template_error'] = $error;
        return $error;
    }
    return '';
} 

I can simply take this section out:

Code:

 if (!$nuke_db) {
        $error = "Error. Please configure 'plugin_template' plugin at aMember CP -> Setup -> plugin_template";
        if (!$_SESSION['check_setup_plugin_template_error']) $db->log_error ($error);
        $_SESSION['check_setup_plugin_template_error'] = $error;
        return $error;
    }

BINGO.. much thanks!
