'Unable to parse URL' errors

Hi guys,

My /error_log file is filled with these errors:

[15-Jul-2014 09:41:47] PHP Warning:  parse_url(/archives/23654/://www.<DOMAIN>.com/feed/feed) [<a href='function.parse-url'>function.parse-url</a>]: Unable to parse URL in /home/<ACCOUNT>/public_html/wp-content/plugins/rename-wp-login/rename-wp-login.php on line 412

The “/archives/xxxxxx/” pages don’t exist, too.
Do you know what’s the issue is, and how can this be fixed?

Thanks in advance.
