Captcha image is not working

[Jolsvi]

Hi,

I have tried to browse some forum about blank captcha image problem, but I haven't got solution yet.

Please help, maybe someone have same issue and could share how to solve it.

 

So I have product review module, and it has captcha feature. But captcha code is not appearing. (attached 1)

When I check the inspect element, it shows (attached 2 & 3):

Notice: A non well formed numeric value encountered in /home/waterfj0/public_html/modules/homecomments/library/Captcha.php on line 76
var captcha_src = "https://waterfilterforfridge.com.au/index.php?fc=module&module=homecomments&controller=captcha&homecomments_captcha&t=0.48374300+1623974623";

 

I follow some forum and try to edit the line 76:

// Use milliseconds instead of seconds
srand(microtime() * 100);      <--- line 76 - change to: srand(microtime(true) * 100);
// Generate CAPTCHA code if not set by user
if (empty($captcha_config['code'])) {
    $captcha_config['code'] = '';
    $length = rand($captcha_config['min_length'],$captcha_config['max_length']);
    $captcha_code_length = Tools::strlen($captcha_config['code']);
    while ($captcha_code_length < $length) {
         $captcha_config['code'] .= Tools::substr(
              $captcha_config['characters'],
              rand() % (Tools::strlen($captcha_config['characters'])),
              1
         );
         $captcha_code_length = Tools::strlen($captcha_config['code']);
    }
}

 

After I edit the line 76, the captcha is showing without image at all (attached 3)

 

Currently the website is running under:

Prestashop 1.6.1.4.

PHP version 7.1

 

Thank you in advance

You need to enable the debug mode of your site and then need to check what is the erorr show. What is your php version and your PrestaShop version. If you are not expert in php coding. I suggest you to hire any professional who can do this task for you within few mins.

 

Thank you
