Admin Panel Warning: Missing notelycategory_meta_box Function

I get the following Warning on my Admin Panel after installing this plugin: Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘twgb_Notely’ does not have a method ‘notelycategory_meta_box’ in /{directory/url}/wp-includes/plugin.php on line 496 On Line 20 of your notely.php is the following line: add_action( ‘add_meta_boxes’, array( $this, ‘notelycategory_meta_box’ ) ); There does not seem to be any other reference to ‘notelycategory_meta_box’ Is there a missing function or was this line mistakenly left in? I’ve commented it out in the mean time as a temporary fix. https://wordpress.org/plugins/notely/ I see you updated the plugin and fixed this. Thank you!
