Widget Positioning help

I've installed Concised IPB Theme on my forum recently (Ref: https://help.forumotion.com/t133402-concise-ipb-theme-for-forumotion-punbb), although I'm having problems with the widget positioning as the widget destroys the appearance of the whole forum. So, I want to ask help from you guys on how to place the widget on the right side near the scroll bar (right:0px;) and placed at the back of the forum if possible. See sample below:

Problem: My forum appearance w/ widget

Hi

Can you please link me to your forum?

@Pizza Boi
Here's my forum url

Hi

The tag that's producing the errors is the width you set for ".pun". Please adjust it accordingly.

I tried to set it by 100% width but it's still the same. I already found a way how to make it work but {ADMIN_LINK} or Administrator Panel link is not located in the right position (otherwise, I will have to force edit it in the template).

Hi

Add an ID for {ADMIN_LINK} and edit it via CSS.

Then, it will be my last resort. XD Thankies.

Last concern: Is there any way I can place the widget at the back of my forum (instead of moving the forum body to the left)? The widget is covering a part of the forum.
