Forum Forum Block Width

[محروم.كوم]

Apologies if the answer to this is already on the forum - but I have searched for an hour and cannot find a solution...

I want to include the Tag Cloud widget on my forum pages - and know how to enable the sidebar and add the widget.
The only problem is I do not like the default 270px width - I want it to be about 180px.

I have gone into the Stylevars, found forum_sidebar_width and altered - It has no effect at all

What am I doing wrong please.

I have found various posts on setting the width - but no one seems to have encountered this... __DEFINE_LIKE_SHARE__
