Details: If you enable the basic builtin RSS Widget Module and set the RSS Feed URL like
http://www.domainname.com/feed/ the widget set the URL only on the little „RSS Icon“ but NOT on the RSS Hyperlink ! The Hyperlink is pulling the Value of $url (www.domainname.com) but not adding „/feed/“ subdir value.
Solution:
- go ../wp-includes/widgets/
- edit with $nano class-wp-widget-rss.php
- go line 81 show title „rsswidget“ href “ ‚ . esc_url ( $link ) . #change here $link to $url
- exit and save..
- check results..
