I tried to install some extensions regarding Ajax search form I would like search in the catalog via ajax, so have suggestions and images in the results (see image) When i Install any extensions, once back in the backend, the menu: system>>configuration don't appear, this is the error message:

"Fatal error: Class 'Magebuzz_Searchautocomplete_Helper_Data' not found in /home/catoccim/public_html/app/Mage.php on line 547"

I have to uninstall the extension for continue working. I tried different extension but the result is the same.


The Data.php Helper is not registered or exists, and Magento trying to load it. This is the reason why you get this error. I suggest you to check if this class exists, and the configuration for helper are properly in this module. To test your class if it exists after you are done with configuration in config.xml for this helper, add a test.php file in your root of website with the followinn content:


        include "app/Mage.php";
        $helper = Mage:helper("your helper configuration for this module");


After you creted this file, open it from url (yourwebsite.com/test.php) or terminal php test.php

  • Hello, tnx for your reply this is the message after run test.php Parse error: syntax error, unexpected ':' in /home/catoccim/public_html/test.php on line 5 – Luca Bernabei Mar 28 '17 at 13:35
