Error On Front End

[jacosky]

Please I don't know if I'm doing this in the right place but I just need help anyhow as I've already searched the forums for my query and found no solution to it yet.

I just made a new install (V2.0.6) on my site but nothing is displaying on the frontend of my site. This is the error I'm getting on the front end - Catchable fatal error: Object of class stdClass could not be converted to string in /home/smssenda/public_html/sms/libraries/joomla/cache/storage/file.php on line 88

My link is http://www.smssenda.com/sms/services/shop

Please someone help asap!
