Make sure that the widget module in your root dir is named 'widgets' not 'silverstripe-widgets'... That was my problem, not they are working great.
OK, I've managed to get the widgets working now; problem was the silverstripe-widgets module, which I updated after reading this thread: http://www.silverstripe.org/general-questions/show/20319 (see Liam's post for link to download - thankyou my friend). Once I updated that module the widgets are working just fine. yee-ha!
I had same issue with urs. Currently, the widgets are unclickable. Luckily, i found your comment. However, the link your provided is broken (actually, Liam's link is broken). Could you please give me a hand on the code? Thanks so much.
