There is an error suddenly started popping up. The error occurs on various part of website like cart area, product detail page etc..
I am running my site on local server. the error is as follows:
Fatal error: Call to a member function getReadConnection() on boolean in app/code/core/Mage/Core/Model/Resource/Db/Collection/Abstract.php on line 134
I have googled the issue but that didn't helped either.
