Kaltura not appearing in the Site Configuration.

Hello !
I have installed kaltura , Previously it was not appearing in the site configuration, now
when i go to the node with a video, it shows an error listed below.

Notice: Array to string conversion in theme_kaltura_metadata() (line 10 of /home/eemindsc/public_html/sites/all/modules/kaltura/plugins/field_kaltura/field_kaltura.theme.inc).

for example
www.eeminds.com/node/1

Any idea about the reason?

Thanks
