CubePoints

It's a great plugin with some issues:
Test Environment:Wordpress 3.9.2+the twentyfourteen theme,without any other plugins.
1. I18n:
1.1 Warning: _() expects exactly 1 parameter, 2 given in xxx\wp-content\plugins\cubepoints\modules\donate\donate.php on line 165
it should be:
 'somethingWentWrongText' => __('Oops, something went wrong! Please try again later.', 'cp');
1.2 the backup.php file should add some ,'cp'to _();
1.3 line 80 of post_authors_points.php should be:
_e('Comment on your post was removed','cp'); and so on;
2. BUGS?
2.1 the ajax user search form on the wp-admin/admin.php?page=cp_admin_add_points page may be have some issue;
2.2 if I activate the Paid content module and set the 'Multiply points earned by' to 2, when some user pay for a post need to pay 10, Cubepoints will deduct 20 points from the user's account.
3.for better I18n:
/**
 * Update Cubepoints database for better i18n support
 * @author suifengtec http://suoling.net/cubepoints-mysql
 * @since 2014.09.09
 */
add_action('init','cwp_update_cubepoints_db_for_i18n');
function cwp_update_cubepoints_db_for_i18n(){
if(get_option('wp_cp_has_be_updated'))
 return;
 global $wpdb;
 $charset_collate = '';
 if ( ! emptyempty( $wpdb->charset ) ) {
 $charset_collate = "DEFAULT CHARACTER SET {$wpdb->charset}";
 }
 if ( ! emptyempty( $wpdb->collate ) ) {
 $charset_collate .= " COLLATE {$wpdb->collate}";
 }
 $charset_sql="ALTER TABLE <code>{$wpdb->prefix}cp</code> DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci";
 $charset_done=$wpdb->query($charset_sql);

This plugin extends myCRED functionality to add different amount of points for comments to different post types.
After activating the plugin, a new section must appear in hooks config in myCRED menu, in this section you can configure the amount of points for comments to each post type and the log entry description.
Only post types with support for comments will appear in the config section.
<a href="https://github.com/Webilop/mycred-post-types-comments" rel="nofollow ugc">The plugin is available in Github</a>. We receive patches to fix bugs and translation files.
TODO: 
– Option to limit points by amount of comments per day/week/month
