I am currently working on a project which is build using 1.1.5. When 1.1.6 is released, I upgraded by framework. But after this, all pages having Cgridview, ajax is not working. I get the following error in firefox error console,
Now that I come to think of it, the first thing to do is to empty your assets folder, because I think the javascript file has changed, so it will need to be published again. Give that a try and let us know if that works.
