eXtplorer - PHP-based File Manager

If only one authentication mode is allowed in the extplorer configuration, the sentence of "You could switch to mode." should not show unless there is more than one authentication method allowed.

For example:

$GLOBALS['ext_conf']['authentication_methods_allowed'] = array('ftp');

FTP is the only allowed authentication method, and yet, I still see the sentence of "You could switch to mode.". This sentence should not show if there is only one authentication method available, as it's very confusing.

Attached screenshot shows "You could switch to mode."
