hello..
i have a problem with widgets..
when i login in the forum the widgets are fine for all members but for the guest widgets are at the end of the forum

Please post your forum's link.

How are they when you're logged in? Can you provide a screenshot of its 'normal state'?

Alright. It's no need. I see what is the problem.
Go to ACP (Administration Control Panel), then choose Display tab, go to Pictures and colors section and click Colors. Then, choose CSS stylesheet tab.
Scroll down to bottom of the textarea with CSS Code and paste this:

Code:

#content-container div#content {
    margin-right: 0;
    float: left;
    width: calc(100% - 270px);
}

The #content div wasn't set to be on the left, and margin does nothing, because it's still div's area.

By the way, I highly suggest to set all the width by % unit. On 1024px wide screens the right panel is like invisible or you have to scroll horizontally, which is a bad idea (forum's design gets broken).

@Ritsu its dosnt work

@MasterSly, okay, I knew that. CSS is not correctly read (calc function), so I suggest to put a script.

Go to ACP -> Modules -> HTML&Javascript section -> Javascript codes management -> Create a new script. Make sure that you have enabled Javascript management.

Title: your choice
Placement: in all the pages
Javascript code:

Code:

$(function() {
  $('head').append('<style id="widget-fix">#content-container div#content {margin-right: 0;float: left;width: calc(100% - 270px);}</style>');
});
