PHP Warning HTTP request failed! HTTP/1.0 404 Not Found

[Sam Hamilton]

Hi, I am new to this community and would be grateful for any guidance you can give.

I am constantly receiving a PHP warning whenever I create a post on my wordpress site. Below is a sample of the warning.

**PHP WARNING
**

html/thegeelongeditioncom/wp-content/plugins/df_social_media/df-social-media-oauth.php on line 533
[11-Dec-2019 02:16:53 UTC] PHP Warning: file_getcontents(https://plusone.google.com/u/0//+1/fastbutton?url=https%3A%2F%2Fthegeelongedition.com.au%2Ftag%2Fpeople-home%2F): failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found

This is on every single post. I can see the URL is missing but it is automatically generated so unsure how to fix the problem.

Below is a snippet of the code containing line 533 as mention in the warning message.

    /**
     * Get Goolge+ ones
     * @return integer
     */
    static function df_get_google_plus_count( $url ) {
        $url = sprintf('https://plusone.google.com/u/0/_/+1/fastbutton?url=%s', urlencode($url));
        preg_match_all('/{c: (.*?),/', file_get_contents($url), $match, PREG_SET_ORDER);
        return (1 === sizeof($match) && 2 === sizeof($match[0])) ? intval($match[0][1]) : 0;
    }

    Any ideas how to rectify this problem? Much appreciated.

Frankly I'd unplug what you use now and plug in a replacement as it appears the plugin you have broke.

That function is trying to connect to Google Plus API to get the plus count of your pages, but Google Plus is dead (https://plus.google.com/about), and therefor 404 http error (page not found, so nothing to count)
Perhaps you can fix it with a plugin update if the author of the plugin made one recently, but if he abondend the plugin, then indeed better to install a more recent Social Media plugin.
