" PHP Notice: Undefined index: price" error causes an unaccesable webpage

Note/disclaimer: I have little experience with php programming

I have a domain hosted on which has one subdomain. On this subdomain i installed MarginBot. When i got to the correct address i noticed the webpage just kept on loading. I checked the server logs and found out they where being flooded with the message:

[Fri Oct 13 20:26:06.405827 2017] [proxy_fcgi:error] [pid XXXXX:tid XXXXXXXXXXXXXXXXXX] [client xx:xx:xx:xx:XXXXXX] AH01071: Got error 'e/XXXX/domains/XXXXX.XX/public_html/marginbot/inc/ExchangeAPIs/bitfinex.php on line 78\nPHP message: PHP Notice: Undefined index: price in /home/XXXXX/domains/XXXXXX.XX/public_html/marginbot/inc/ExchangeAPIs/bitfinex.php on line 78\nPHP

I looked up the file bitfinex.php and went to line 78. Here below is the function that line 78 belongs to:

`    /* Data posting query, for detailed API calls */
     function bitfinex_query($method, array $req = array()) {
        // API settings

        $req['request'] = '/v1/'.$method;
        $this->nonceInc += 1;
        $req['nonce'] = (string)$this->nonceInc;
        if($req['price']){$req['price'] = (string)$req['price'];}

        // generate the POST data string
        $reqData = base64_encode(json_encode($req, true));
        $post_data = http_build_query($req, '', '&');
        //print_r($post_data);
        $sign = hash_hmac('sha384', $reqData, $this->apiSec);

        // generate the extra headers
        $headers = array(
            'X-BFX-APIKEY: '.$this->apiKey,
            'X-BFX-PAYLOAD: '.$reqData,
            'X-BFX-SIGNATURE: '.$sign
        );`

Further information: -When installed MarginBot i then configured my bitfenix account using the MarginBot webpage gui. (I could still access and use the webpage -I made a second user account

After the things mentioned above the webpage became unaccesable. I'm guessing i'm making an obvious mistake here which i am sure one of you can assist me with.

Further more an other error popped up in the server logs:

[Fri Oct 13 20:26:23 2017] [proxy_fcgi:error] [pid XXXXX:tid XXXXXXXXXXXXXX] (70007)The timeout specified has expired: [client XX.XXX.XX.XXX:XXXXX] AH01075: Error dispatching request to : (polling)

However i'm betting this is merely the result of endless loading due to timeout
