"Base table or view not found"

If you are seeing this error after installation then Magento is not able to update the database correctly with SQL script. The easiest way to resolve will be to enter the SQL script manually using phpmyadmin or similar software:

DROP TABLE IF EXISTS `iwd_notification`;
CREATE TABLE `iwd_notification` (
 `entity_id` int(11) NOT NULL AUTO_INCREMENT,
 `title` text,
 `description` text NOT NULL,
 `severity` int(2) DEFAULT NULL,
 `<g>url</g>` text,
 `date_added` datetime NOT NULL,
 `view` int(1) NOT NULL DEFAULT '0',
 `out_id` int(11) DEFAULT NULL,
 PRIMARY KEY (`entity_id`)
