MailChimp API V2.0 SSL error solution

I got this SSL error while trying to use MailChimp API V2.0 in my localhost.

Fatal error: Uncaught exception 'Mailchimp_HttpError' with message 'API call to lists/list failed: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed' in C:\Installation\xampp\htdocs\mailchimp-test\Mailchimp.php:192 Stack trace: #0 C:\Installation\xampp\htdocs\mailchimp-test\mailchimp-api.php(16): Mailchimp->call('lists/list', Array) #1 {main} thrown in C:\Installation\xampp\htdocs\mailchimp-test\Mailchimp.php on line 192

To resolve this, you can try any of the methods below.

Method 1:
  • Download cacert.pem file from here: http://curl.haxx.se/docs/caextract.html
  • Save the file in your PHP installation folder. I am using xampp. So I saved it in C:\Installation\xampp\php\cacert.pem
  • Open your php.ini file and add this line:
    curl.cainfo="C:\Installation\xampp\php\cacert.pem"
  • Restart your Apache server and that should fix it.
Method 2:
If you are unable to edit php.ini file, there is a quick workaround.
  • Open the MailChimp API file (it's most likely named Mailchimp.php or MailChimp.class.php).
  • Look for statements starting with "curl_setopt".
  • Right below the set of "curl_setopt" statements, add this line:
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
Both methods should work but method 1 is probably more reliable.

    This can be done without editing the wrapper class file.

    Just pass an argument while initializing the Mailchimp class.

    $mailchimp_obj = new Mailchimp ( 'YOUR_API_KEY', array('ssl_verifypeer' => false) );

    Method 2 didn't work, so I tried first one for local machine - and it worked.
    Hope, it will work after deploy :)

      I got this error only when working in the localhost. In the remote server, it wasn't an issue. Let me know if yours still continue to work after the deployment.

      Not sure if I understand completely.
      However in your .htaccess, try this:
      RewriteEngine On
      RewriteBase /mcapi2-php-examples/

    Thank you very much, method 2 worked for me, i just had to make a small change for the v 2.0:

    Instead:
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    Use this:
    curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, false);

    In Mailchimp.php there is curl_setopt($this->ch, CURLOPT_FOLLOWLOCATION, true);
    & I set FALSE but still showing:
    API call to lists/list failed: SSL certificate problem: unable to get local issuer certificate

    Free SSL ought to not be used for protected payments.

How to resolve 'res://ieframe.dll/acr_error.htm#' error (Internet Explorer stopped working while viewing a website)

While testing a website I was developing, I got an error message saying "Internet Explorer has stopped working". This is followed by this line added before the URL: res://ieframe.dll/acr_error.htm# . I was using Internet Explorer 11 in Windows 7 64-bit machine. I tried disabling all add-ons in IE but that did not resolve the issue. I've found this solution to my problem: From Tools menu, open "Internet options". Go to the Advanced tab. Under "Accelerated graphics", tick the box that says "Use software rendering instead of GPU rendering". Click Apply and Ok. Test your website. You might need to restart your computer if it does not immediately show any effect. This worked for me.

htaccess: Redirecting multiple domains to the main domain

Let's say this is the main domain: mywebsite.com.au And you'd like to redirect several other domains that you have purchased to this main domain.The steps shown below redirects all www, non-www, http and https variations and also matches the internal pages. Step 1: Go to your DNS provider's website and point each of those purchased domains to the server that is hosting your main domain. In other words, add the IP address of your hosting server in the A record. Step 2: Log in to your WHM. Then park each domain on top of the main domain. You may be able to do this in cPanel > Aliases but I haven't tried. Step 3: If you have AutoSSL enabled, all the additional parked domains will automatically get SSL added. This may take some time. Alternatively, you can go to WHM > Manage AutoSSL and Run AutoSSL Check. Step 4: Add your parked domains to your .htaccess file as shown below. Note the "$" at the end of this line: ^www\.mywebsite\.com$ . This ...

Removing index.php in Codeigniter using XAMPP on Windows

Using the method below, you can access your site http://localhost/Mysite/index.php/welcome without the index.php like this: http://localhost/Mysite/welcome I did this in Code Igniter 2.0.3 using XAMPP 1.7.1 on Windows 7. Create .htaccess file in the root folder of code igniter. I got the code below from http://codeigniter.com/wiki/mod_rewrite/ . Make sure you use your site folder name in Rewrite Base below:     RewriteEngine On     RewriteBase /Mysite/     #Removes access to the system folder by users.     #Additionally this will allow you to create a System.php controller,     #previously this would not have been possible.     #'system' can be replaced if you have renamed your system folder.     RewriteCond %{REQUEST_URI} ^system.*     RewriteRule ^(.*)$ /index.php?/$1 [L]         #When your application folder isn't i...
