 * Hi,
 * Yes, but other warnings now:
 * > Deprecated: Required parameter $rss_url follows optional parameter $index in
   > my-domain\wp-content\plugins\rss-feed-widget\inc\functions.php on line 311
   > 
   > Deprecated: Required parameter $widget_sub_array follows optional parameter
   > $index in my-domain\wp-content\plugins\rss-feed-widget\inc\functions.php on
   > line 311
 * But these warnings were only displayed once, after updating plugin.

 * Usually when we turn debug mode ON, like you did, we see numerous warnings from
   different plugins, are you reporting all of them or only to me? Please try the
   latest version I have just released for you.

 * Yes, most of the times I do inform developer when I stumble upon something in
   his or her plugin. And I appreciate it if a user of my own theme/plugin informs
   me as well.
 * Will update plugin tomorrow and let you know.
