Feeds from ebdz.xyz not working

Feeds provided by a forum built with MyBB do not seem to be retrieved correctly or parsed correctly.
example of URL <![CDATA[EmuleBDZ]]>
To be honest Feedly or Innoreader are not doing better, but the RSS reader of Vivaldi do retrieve it OK, below the beginning of the code retrieved (I can provide the full version as needed).
Should Newsblur be able to get it right, I would really consider a paid subscription…
Thanks a bunch

I don’t know for sure but it looks like the feed itself is empty:


Thanks for the reply and for investigating.
I understand. As the feed works in Vivaldi browser that includes a RSS/Atom client maybe it’s done by Vivaldi in a non standard way, I would not know. I shall remain with that solution then.
