I am getting a conflict with LyftenBloggie and the Sourcerer plugin extension for Joomla.

Here is the error code:
Catchable fatal error: Object of class stdClass could not be converted to string in /hermes/web06/b2076/hy.poet/plugins/system/sourcerer.php on line 624

The error occurs when you try and edit or view a page from the LyftenBloggie menu bar on the edit pages.

Suggestions for resolution?
