I have installed and configure my wordpress in my magento site using Fishpig extension.
In magento admin, the configuration of Fishpig extension shows perfect.
But when I am running the wordpress route in frondend, it is showing Fatal error and not displaying wordpress content anymore.
Attaching the screenshot of that page. And the error I got is:
Fatal error: Call to undefined method Mage::getResourceHelper() in /[MY_DIR_PATH]/app/code/core/Mage/Core/Model/Resource/Db/Collection/Abstract.php on line 534
Any help is appreciated.
This was fixed by upgrading to the latest version (18.104.22.168 at the time of writing).
