directory theme creates errors with file uploader plug-ins

when using the directory plugin and its accompanying theme in conjunction with file uploaders (at the moment I'm using "Inline Upload" v1.7.9 and wordpress 3.4.1 I'm getting the following error:

Fatal error: Call to undefined function dp_posted_on() in /home/m******/public_html/ddp/directory/wp-content/themes/default/loops/loop-single.php on line 7

the same is true for ftp file uploader and dropbox uploader. please advise.
