That’s strange. Actually notices should not cause a blank page.
From which version did you try to upgrade?
RecipePress reloaded 0.6.0 does not require a database upgrade if you upgrade from 0.5.x. Database upgrades are only required from 0.3.
After looking on your site you also seem to have another problem. Please also post the error message you get when looking an a recipe on the front page.
