I just installed the YD Recent Posts widget and made changes in the plugin's Settings page ... but when I try to update the settings, the page doesn't refresh on the same page (ie. admin / plugin's settings page) and update the changes ... instead it loads an Error 404 page in the theme's front-end.
So I am unable to make any changes in the Settings page.
Any idea why this is happening and how to fix this?
Thank you,
Ben
