Thanks Eric,
I have run through that checklist, cURL is enabled but still those two feeds are not fetched, I get the following error in the RSS Debugger screen. What puzzles me is that the feed from https://chess24.com/en/read/news.rss is received normally as is another one. Any ideas why one valid feed is received whilst another is not? I imagine there is something wrong at my end but I can not find as yet.
