Fatal error: Call to undefined function curl_init was created by nomi

Posted 8 years 3 months ago #14839

Hello all,
We had to reinstall the template after an Upgrade. The template Worldnews was purchased at 16.5.2016.
Now i could install joomla by using quickinstall (with example Pages). I can login to backend but in the frontend (index.php) i am getting this error.
"
Fatal error: Call to undefined function curl_init() in /home/mydomain/public_html/stage3/modules/mod_rokstock/lib/googlestock.class.php on line 92
"
Line 92 contains:

Code:

$ch = curl_init();

The Parameter starts from line 90

Code:

function curl($url, &$output, $strip = false)
   
 {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
        curl_setopt($ch, CURLOPT_TIMEOUT, 60);
        $output = curl_exec($ch);
        if ($strip) $output = substr($output, 4, -1);
        $httpinfo = curl_getinfo($ch, CURLINFO_HTTP_CODE);

        curl_close($ch);

        return $httpinfo;
    }

I am not very strong in PHP but it seems to be a problem which never came before in old envoirement.
Could some have look in the file and give me some Hints ?
Big THANKS
