In case of issues
Administration display is wonky
On first load, pages might look weird: because your web browser caches files, it is probably using the old CSS and JavaScript files instead of the new ones.
You must reload the page several times, or even empty your browser's cache, in order to get the correct interface. Read how to clear your cache here: http://support.google.com/accounts/bin/answer.py?hl=en&answer=32050.
Module page is not updated
Reloading the page twice (press F5) should fix the issue
Default theme is not working anymore
The name of the default theme has been changed from "default" to "prestashop" . If you were using the default theme, rename the default theme's folder from "prestashop" to "default", and everything should work again.
Some modules are not working
When an installed module is not giving the expected result, try uninstalling it, then install it again.
Incompatible module
In some rare cases, some modules are not compatible with new version of PrestaShop. You should contact the company / person that provided you with this module to request a few code changes to bring it up to date.
