Problem setting up new threshold with cacti 0.8.7b

[gabar]

Hi,
recently I updated my cacti version from 0.8.6i to 0.8.7b and now I can't define new threshold (while the old thresholds are working and, most of all, editable). Specifically when I try to set up a new threshold clicking on "data sources" link, I obtain a page when the "template name" is NOT linked so I can't click on it to define the threshold. This seems to be very strange because in cacti version 08.6i that link was linked

My thold version is 0.3.2 and my plugin architecture version is 2.0

Can someone help me to resolve this problem?

Thanks in advance
Gabriele.

P.S. I tried to upgrade my thold version but I found many other problem with version 0.3.9 so I prefer to use the version 0.3.2
