Domain Mapping - Missing argument 2 for domain_map::swap_mapped_url()

Hi there,

I have an error message which generated from the Domain Mapping plugin.

Warning: Missing argument 2 for domain_map::swap_mapped_url(), called in /home/webencla/public_html/wp-content/plugins/sitewide-privacy-options/sitewide-privacy-options.php on line 504 and defined in /home/webencla/public_html/wp-content/plugins/domain-mapping/classes/class.domainmap.php on line 1027

And I can't seems to change the privacy and set a password as well because the Sitewide Privacy Options execute this error message:

Let me know how can I fix this. Cheers!
