user siteinfo not working (greyed out)

[JStyle21]

Hi,

I've tried adding a user siteinfo rule, i even used a general regex just to test, something like .*url.*
but i can't get it to work, i'm sure the xpath works since i tested it in the dev tools.
I don't see the green button or that it is on, any idea what could be the problem?

Alternatively
i tried add a rule to the global siteinfo db but i couldn't register since i don't know how to pass the OpenID login (i've tried many times)

Ok, i can see the test: of my local rule in the log list of the extension so at least that means the regex works, but for some reason the xpath doesn't? is the syntax really different from the dev console in firefox? as far as i can see from other public rules the syntax i used is the same.

Any other way to debug it or changes from the regular way things work?
