Just to confirm... the following is only applicable for upgrading addons, correct? It is not required to use upgrade of Xenforo itself from the control panel?
And if you do not use the upgrade from the control panel feature, that line should either not exist or be disabled in config.php?
Just want to clarify and make sure I'm reading this correctly.
Installing or upgrading an add-on
Control panel installation (2.1+)
If you are running XenForo 2.1 or newer, you may be able to install or upgrade an add-on by uploading the zip file directly into the control panel. This requires a compatible server configuration and a change to the src/config.php file.
To enable this feature, you must first add the following line to the src/config.php file:
$config['enableAddOnArchiveInstaller'] = true;
And if you do not use the upgrade from the control panel feature, that line should either not exist or be disabled in config.php?
