Could you please help me with the version of your WordPress installation? I might be able to help you better this way.
same error with version 4.1.1
Hi desaboye. I have tested this plugin on several environments and I can tell you that the error you are receiving is because of an outdated PHP installation on your server.
Line 17 in mixpanel.php is
namespace jittarao {
..so now I think that you have run into this error because you are running with a PHP version older than 5.3 (PHP 5.3 was released in June 2009).
Can you tell me the version of PHP you are running? Here’s a plugin to do it if you’re not sure how to do it manually.
Also, can you tell me where your site is hosted? Do you do it yourself?
If yes, I recommend you to upgrade to the latest PHP release.
Get back to me if the issue still persists. Thanks for using the plugin 🙂
