Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'rss_post_thumbnail' was given in /data/24/2/124/66/2287881/user/2514207/htdocs/wpblog/wp-includes/plugin.php on line 166
Why does this message show up in Reader feeds? It used to show a brief segment of my blog now I get a warning message.
Have you tried:
- deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
- switching to the Twenty Ten theme to rule out any theme-specific problems.
- resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
- re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.

Yikes! All that to figure out which is causing the warning message? I'll get to work. Thanks on pointing me toward a solution.
