Meta value are not listed after update

I get this error when I go to the plugin.

WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ” at line 1 for query SELECT * FROM wp_users LIMIT 0, made by require_once(‘wp-admin/admin.php’), do_action(‘users_page_user-meta-manager’), call_user_func_array, umm_ui, UMM_UI->display_module, UMM_UI->prepare_items, umm_get_users, referer: https://mywebsite.com/wp-admin/users.php?page=user-meta-manager&orderby=user_login&order=asc

Is this issue with the free or pro version?

I found the bug. This is fixed in version 3.4.4.

It’s the free version, where can I get the 3.4.4?
