Two Errors in theme header when using Infinite SEO

Error in theme header when using Infinite SEO. I am getting these errors on my multisite project on the front end after installing and activation of “INFINITE SEO”:

Warning: explode() [function.explode]: Empty delimiter in /home/xxxxxxx/domains/xxxxxxxxxxx.com/public_html/wp-content/themes/striking/framework/functions/filter.php on line 51

Warning: Invalid argument supplied for foreach() in /home/xxxxxxxx/domains/xxxxxxxxxxxx.com/public_html/wp-content/themes/striking/framework/functions/filter.php on line 53

When i deactivate the plugin there is no error coming up, it works fine.

Please help!
