Question [solved] Problem with width of kunena forum on my joomla template

Hi there,
I have problem with width of kunena forum on my site. It looks like that and I would like make kunena to be on whole width of my template. How to delete this empty space on right side?

If it wolud help you to help me, HERE * is a package with movAMP (portable server with PHP and MySQL) with installed Joomla + kunena + theme I use.

*package is in Polish, but it should be no problem

user: admin
pass: admin

I couldn't access the package. This is definitely a problem caused by your Joomla! template. From the screenshot my guess is that the template right divs aren't collapsing when empty. That said, I would really have to see a working demo to know what exactly is causing the problem.

There is correct link:
wimim.j11.pl/pliki/joomla1.5.11_and_kunena1.5.3_PL.rar

Hi again kamil_w,
I may need you try try a few things. First off try this it'll solve the initial and obvious gap on the right. In the local site Joomla! template css: templates123wd-j15-8csstemplate.css change

div#maincolumn_full {template.css (line 340)
float:left;
padding:0 10px;
width:708px;

to

div#maincolumn_full {template.css (line 340)
float:left;
padding:0 10px;
width:98%;

Other divs should be changed to the % widths except the main body div which can stay in pixels. Check for yourself and report any other problems

Thanks a lot! Works great.

EDIT: I have found another problem:
When I click on button moving page to the bottom, the kunena menu looks like on enclosed image.

EDIT2:
OK. I have changed template to MOC and everything is OK.
