Migrating from sencha 2.1.1 to 2.3.1 gone wrong.

Hi there, well I believe the title is self explanatory, just remind to say that i didn't have much time to dedicate to this but it seems there is no good place to start on this, what I did is to replace the sencha touch folder for the newest one and my list items get all mixed up and what I can see is just a bunch of convoluted text because all items are in one line :S



Thanks in advance!
