Thanks for your reply. I have marked this thread as solved since the solution was to install the php-xml parser module.

sudo apt-get install php-xml

SimplePie doesn’t throw an error in this scenario so that’s why it was hard to find the solution.

This code is working:

$c = curl_init();
curl_setopt($c, CURLOPT_URL, 'https://en.blog.wordpress.com/feed/');
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($c);

I think fetch_feed() is using curl – so why is not fetch_feed() working for me?

Please advice.

Thanks for reply. I have installed and activated health-check plugin. I couldn’t find anything problematic about my install, except it recommends me to update to PHP 7.2 (I’m using PHP 7.0.27). See info below.

I used the health-check troubleshoot mode to disable all plugins and themes – except the code above. However, my test code still doesnt output feed data.

Not sure what to do now. I’m pretty sure it is not my server that has problems, since curl from the command line is working. Also, downloading and installing plugins from within wp-admin is working. So fetching external data is working. For some reason external data can not be fetched using the fetch_feed() function.

Any ideas on how to proceed?
