[Plugin: WP Render Blogroll Links] Help with Webpage Error Message: ‘postboxes’ is undefined

Need help with this error message that appears in admin backend once I click on the WP Blogroll Link info page:

Webpage error details

Message: ‘postboxes’ is undefined
Line: 316
Char: 5
Code: 0

Is there something I can do to fix this or do I have to wait until the next update of the plugin.
