Repeaters bug after upgrading to PW 3

[CarloC]

Hi everyone!
this is my first topic and I need to say thanks to @ryan and all the other contributors for this incredible framework that changed my life as a web dev!

But now I go to the point. I developed a project with pw 2.7 and it worked like a charm.

Today i'm trying to update the project to pw3 on a local environment, to test that everything will continue working after the upgrade, and that's not the case.

The major bug I'm encountering is that repeater field doesn't work properly.

Existing Repeater field
This is what I see when I try to edit a page that already has a repeater field (Brand concepts) with some elements:

If I click on one of the "... blocks" nothing appens.

New repeater field
If I create a new repeater field and assing it to a template, when I open a page with that template I see the new repeater field, but the "Add new" link, to add a new element, doesn't work. I click it and nothing appens.

I never had this kind of strange behaviours in PW, and this is one of the reasons why I consider it the best cms/framework I've ever used.

I hope you can help me.
Thank you!
