Class 'EaDesign_PdfGenerator_Helper_Data not found

Question

I am very new to magento, I am trying to install "Invoice PDF generator" extension. I installed it through the magento connect, after pressing install button I got message like "Clear cache successfully".

After this message I pressed refresh button and then return to admin link. But after clicking on that link I am facing fatal error like

Class 'EaDesign_PdfGenerator_Helper_Data not found in E:\wamp\www\leeveNew\app\Mage.php on line 547

Can anybody please tell me if I done anything wrong and suggest any solution for it.

Note : My magento version is 1.9.0.1.

Answer 1

you need to disable extension from app/etc/modules/ then you need to remove var/cache folder then try in admin panel will work.
