The Zurb Foundation base theme requires jQuery 1.7+ to work. Thankfully, we have the excellent jQuery Update module to help out with that.
Please refer to the attached screenshot for reference on the settings form.
- Enable the jQuery Update module
- Go to Configuration -> Administration -> Development -> jQuery Update
- Select "1.7" or "1.8" in the jQuery version select box
- Click on "Save configuration"
If the above steps were followed correctly, Drupal should now be using jQuery 1.7 or jQuery 1.8 and working flawlessly with the Zurb Foundation base theme.
