At some point the variable to output the website info in the copyright area in the footer was incorrectly changed to "{$_conf.jrCore_system_url}", so nothing is output. It probably should be "{$_conf.jrCore_system_name}". See attachment.
You might take a look throughout the footer code as there are other issues. For instance the twitter link is malformed: https://twitter.com/{$_conf.bbElastic2_twitter_url is doubling the "https://twitter.com/" so you get an error. The other social links are formed the same way.
