I'm running the last versions of WP and Jetpack. My comments are closed for all articles, but the WordPress option is set to allow them. I don't know why the comment form is disabled.
I'm receiving a lot of warnings like the next one. I'm thinking my situation is related to jetpack plugin. Jetpack Comments module is not activated.
PHP Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'jpcarousel_auto_close_comments' was given in .../httpdocs/wp-includes/plugin.php on line 199
Thank you for any useful reply!
