This one is a bit tricky to debug. You'll need to PM me some more info.
Open system/tastyigniter/config/constants.php and look for TI_DEBUG, set it to TRUE.
Then go to the menu options in admin, click the green icon bottom left and take a screenshot or copy the 'blue' DATABASE section, do that for the storefront menu page as well. Don't forget to change TI_DEBUG back to FALSE for security, and send the screenshot via PM
