Greetings again! I found a conflict with the following plugins:
Simple Facebook Connect: http://wordpress.org/extend/plugins/simple-facebook-connect/
Simple Twitter Connect: http://wordpress.org/extend/plugins/simple-twitter-connect/
These plugins are modular and function fine with the Role Scoper plugin EXCEPT the module plugins that allow users to leave comments on posts without logging into their WP account, but instead using Facebook or Twitter accounts. I'm not sure why Role Scoper conflicts since I have WP set to accept comments from anyone; however, when Role Scoper is activated, the comments area of each post throws the following error.
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'stdClass::has_cap' was given in/home/p4x/www/www/wp-includes/capabilities.php on line 1067
For now I've just disabled the SFC-Comments (Facebook) and STC-Comments (Twitter) modules because I need Role Scoper to work more than I wanted the convenience of using FB and Twitter accounts to leave comments.
Thanks for all your work on Role Scoper!
in Jesus,
Scott
