Cortex has support for certain 3rd party mods and plugins for many game servers. If your administrator installed one of these plugins on your server you will see an Edit Plugins icon next to your instance on the instances page. Click this button to bring you to a page where you can enable or disable use of that plugin on your server. To enable or disable the plugin click or un-click the checkbox next to it on the plugins page and click Save.
Many plugins have their own configuration opions. To edit a plugin's config select the plugin in the dropdown list on the bottom of this page and click Next. If your plugin does not have any config options then a page showing plugin info is displayed. If your plugin has options for you to set then a form is displayed to edit your plugin. These forms look different depending on the plugin you're working with. Click the Save button to save your plugin settings. In order for your changes to take effect you may have to restart your instance after editing your plugin.
