RSS Feed not working

After adding RSS feeds I can see a list but after selecting an item, the only output i get is "null".

Please specify the feed url

I wasn't able to get any working so far

https://www.reddit.com/.rss
http://9gag-rss.com/api/rss/get?code=9GAGHot&format=2
http://9gag-rss.com/api/rss/get?code=9GAGHot&format=1

All of these links worked for me.

Can you review the response obtained in (modules/Rss/models/Record.php > function validateRssUrl > fetch_rss)

Thanks again for your help, I was missing some files.

Warning: require_once(libraries/magpierss/rss_fetch.inc): failed to open stream: No such file or directory in /vtigercrm/modules/Rss/models/Record.php on line 10

Status changed to reopened

That actually didn't resolve the issue :/ Both files exist, and I am still getting this error.

Here is my response:

{"success":true,"result":{"html":null}}
