RIP reduxframework.com/feed.

wp-mail-logging/lib/vendor/redux-framework/core/dashboard.php

has an rss feed hardcoded and is generating this error:

PHP Notice: A feed could not be found athttps://reduxframework.com/feed/; the status code is404and content-type istext/htmlin /wp-includes/class-simplepie.php on line 1728

a simple fix might be to change it to the valid feed ie. https://redux.io/feed/

change line 27 of wp-mail-logging/lib/vendor/redux-framework/core/dashboard.php

from
https://reduxframework.com/feed/
to
https://redux.io/feed/

..until a later version of redux is included.

cheers
