Need Help Asap!

You can create custom template for pages: https://codex.www.ads-software.com/Pages#Page_Templates

Or simply you can create a custom page-pageslug.php ??

how can I do that?

your link seems confusing.

Confusing? Try reading with calm ??

BTW probably in your theme you have a page.php which call the function
<?php get_sidebar(); ?>

If you create a php file called:
page-slugofthepageyoudontwanthesidebar.php

You can remove that function…

if I create it where would I upload it..? in the cpanel? just would like to confirm coz this would be my first time

And the link that you gave is designed to work on a twenty eleven theme

The link I gave you is for all kind of theme.
When you have your .php file you have to upload it via FTP in wp-content/themes/yourtheme

I just did, but it doesn’t seem to work

this doesn’t seem to work can anyone help me with this?

did you make a page template?

what is the code of it?
(please paste the code into a https://pastebin.com/ and post the link to it here)

what is the result?
to illustrate what you have so far, please post a link to your site, to the page without sidebar.

if you are new to WordPress, start be reading:

here’s the link

this would be the website. But I cant seem to remove the divider line in the sidebar. I only used its usual page template and removed the get_sidebar code

<?php get_header(); ?>

<!– begin colFull –>
<div id=”colFull”>
<h1><?php the_title(); ?></h1>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

<?php the_content(); ?>

<?php endwhile; else: ?>
<p><?php _e(‘Sorry, no posts matched your criteria.’); ?></p>
<?php endif; ?>
</div>
<!– end colFull –>

<?php get_footer(); ?>

That image is a background of your div#content

nope it’s not. My content is just the big box with the notification words inside.

Oh, what do you mean about div#content
