Plugin Page Empty -- No Dropdowns

[pfabri]

Expected Behaviour

The plugin page displays plugins available for installation in a drop-down menu.

Actual Behaviour

No drop-downs are displayed at all.

Attempted Solution

Placed allow_url_fopen = 1 and allow_url_include = On both in php.ini and .user.ini, but the problem still persists, unfortunately.

Config

Linux server with PHP7.

The function tries file_get_contents first when available (see https://github.com/AcuGIS/Escher/blob/master/libraries/Escher/Controller/Action/Helper/Addons.php#L211), so I don't understand the issue. Does file_get_contents($url) work? Can Omeka access this url (https://omeka.org/add-ons/plugins/) (https, not http) ?

[pfabri]

Would you please be able to provide and example code to test if it works? Many thanks!

$url = 'https://omeka.org/add-ons/plugins';
if (ini_get('allow_url_fopen') && ini_get('allow_url_include')) {
    $result = file_get_contents($url);
    if (empty($result)) {
        echo 'Unable to fetch page.';
    } else {
        // This should be the html of the page.
        echo $result;
    }
} else {
    echo 'Fetch via php curl if extension enabled.';
}

This is a code for an external script.
