wat do u want to disable “archives”??? or sidebar?? plz specify
Youll need to edit some template files like index.php, page.php, single.php. All files that are including sidebar.php. Can you post your index.php code?
I have never used imageshack.us so don’t know if they are a hosting services provider, or what, but I have seen that picture before on a WordPress site. The site was hacked and that picture was inserted into the background.
What is your site URL?
Have you tried just adding a blank text widget to your sidebar?
