Front-end widgets don't work for me

Hello

First of all, thank you very much for this excellent software

Now, let's talk about my problem.

I work with airtime 1.7.0
Everything works excepts the front-end widgets. I have to say that i enabled the preference "Allow Remote Websites To Access "Schedule" Info" but nothing is written on my html page.

Anyone has the same problem ?
Anyone knows how to solve this ?

Thank you very much in advance.
