what’s the problem ?
sometimes with errors. like this image :
please check . thanks
On the dashboard there is a widget that fetches the Matomo RSS feed to display news and updates.
The error shows that the plugin didn’t get back a proper RSS feed, but something else. So either something is interfering with the connection or the Matomo website showed an error just as you loaded the feed.
If you don’t care about news, you could just disable the RssWidget plugin.
