Open applications\links\sources\Link\Link.php and find:
$return['url'] = new \IPS\Helpers\Form\Url( 'link_url', ( $item ) ? $item->url : '', TRUE, array( 'allowedProtocols' => array( 'http', 'https' ) ), function( $val ) use ($item)
{
if( \IPS\Request::i()->do == 'submit' )
{
$count = \IPS\Db::i()->select( 'COUNT(*)', 'links_links', array( 'link_url=?', $val ) )->first();
if ( $count )
{
throw new \InvalidArgumentException('link_in_use');
}
}
} );
Change to:
$return['url'] = new \IPS\Helpers\Form\Url( 'link_url', ( $item ) ? $item->url : '', TRUE, array( 'allowedProtocols' => array( 'http', 'https' ) ) );
