i keep getting the "could not update error" 

some help me.... please

Hi Dennis,

Have you changed something in your LocalStorage entities that may cause problems with existing data? (Ex: if you have an entity attribute that is a Text and change it to Integer you may run into an upgrade error because the values in the LocalStorage may not be convertible to Integer). Try reverting those changes and fix the data first.

As a last resort, you may clear your browsing data, but that will wipe what you have in the browser LocalStorage.
