Hello,
I’ve got the following error:
> Warning: First parameter must either be an object or the name of an existing class in /www/htdocs/w011e2a4/webdata/wordpress/wp-content/plugins/wp-discourse-0.6.6/lib/discourse.php on line 507

This happens since I’ve changed the subdomain of our WP site from sandbox._… to www._… The issue shows up when publishing a new post.
All the other sites are working probably. I didn’t notice any other issues.
The post by itself is showing this error:
> Warning: First parameter must either be an object or the name of an existing class in /www/htdocs/w011e2a4/webdata/wordpress/wp-content/plugins/wp-discourse-0.6.6/lib/discourse.php on line 507
Any clue?

Have you tried to simply uninstall and reinstall the plugin?
