Getting Zend and Apache Related Errors

I’m getting all kinda of apache error from the ‘like’ plugin. The weird part is that they display on the dashboards of other plugins like WP-stats and google analytic. Why is this happening? Please help me to resolve. I have an apache error log available if the developer tells me where to send it.

Fatal error: Internal Zend error - Missing class information for in /home/XXXXXX/public_html/wp-content/plugins/like-button-plugin-for-wordpress/include/gb_generate.php on line 22
