I built a WordPress plugin following Alessandro Castellani's tutorials with no problem.

However, when I built a second plugin and activate it, for some reason it overwrites the first one. In the sidebar, I get two links for the same (the second) plugin, whereas the first one does not appear. Even if I deactivate the first one, the second plugin appears as double.

Desired Behaviour: The two plugins work and act as separate units.

Current Behaviour: They seem to be overlapping and taking settings from each other and the second one removes the first one from the sidebar. What appears is the second plugin twice.

I have a different name for the plugin and reference this throughout

/**
 * @package PluginNumberTwo
 */

Could the problem be because my __construct function within the BaseController is nearly identical?

First Plugin:

$this->plugin_path = plugin_dir_path( dirname( __DIR__ ) );
$this->plugin_url = plugin_dir_url( dirname( __DIR__ ) );
$this->plugin = plugin_basename(dirname(dirname(__DIR__))) .'/first-plugin.php';

Second Plugin:

$this->plugin_path = plugin_dir_path( dirname( __DIR__ ) );
$this->plugin_url = plugin_dir_url( dirname( __DIR__ ) );
$this->plugin = plugin_basename(dirname(dirname(__DIR__))) .'/second-plugin.php';

One potential problem is that some of the functions have the same names.

public function register()
public function addPages( array $pages )
public function addAdminMenu()
public function setSettings( array $settings )
public function setSections( array $sections )
public function setFields( array $fields )
public function registerCustomFields()

Would this potentially cause the problem?

Thanks!
