I've created a custom module with an Observer to log every product change on a log file.
The Observer is listening on the event catalog_product_save_after. I've created the folder for my namespace under app/code/local and so I defined it on the configuration files.

My problem is that Magento is trying to load the module under the namespace Mage, and I don't know the reason for this behavior.

Here are the error log:

2018-01-05T09:06:51+00:00 ERR (3): Warning: include(Mage/Mynamespace/Editlog/Model/Observer.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/magento/lib/Varien/Autoload.php on line 94

2018-01-05T09:06:51+00:00 ERR (3): Warning: include(): Failed opening 'Mage/Mynamespace/Editlog/Model/Observer.php' for inclusion (include_path='/Applications/MAMP/htdocs/magento/app/code/local:/Applications/MAMP/htdocs/magento/app/code/community:/Applications/MAMP/htdocs/magento/app/code/core:/Applications/MAMP/htdocs/magento/lib:.:/Applications/MAMP/bin/php/php7.1.8/lib/php') in /Applications/MAMP/htdocs/magento/lib/Varien/Autoload.php on line 94

Does anyone know why is looking for the observer under the Mage directory ? Do I have to put there my module?

  • Do you have a config.xml in the etc/ folder of your module? Do you also have a properly formatted Mynamespace_Editlog.xml file in app/etc/modules/?

  • In your config you can specify your codePool, make sure it is set to local. Commented Jan 5, 2018 at 10:01
  • Yes I have this two files properly formatted, and the codePool is set to local Commented Jan 5, 2018 at 10:11
  • Could you add the config files to the post so we have some more information to go off, cheers. Commented Jan 5, 2018 at 10:29

I found the error. I made a mistake on the config.xml: I didn't define the models tag.

After I defined it, the module is loaded correctly.

The next time I will also post the whole configuration files.


Please try changing the following line in config.xml from:



  • Changing to full class name makes it impossible to rewrite the observer.
