Product Images & Extensions not showing after Magento upgrade/migration

Question

I upgraded my Magento from 1.5.1 to 1.7 using a fresh install as described here: http://www.customerparadigm.com/magento-development/upgrade/how-to-upgrade-magento/

For some reason my product images and extensions are not showing. I refreshed/flushed all caches, and reindexed.

Any idea why this might be?

I did run Magento/login to admin before copying the extension and media files over, but I am not sure if that should impact it.

Answer 1

1) check /media and app/etc and /var folders permissions 2) check extensions list at Admin - System - Configuration - Advanced 3) check if you can access some media image by direct url
