That shouldn’t cause a white screen.

At this point you should probably contact your hosting company. Without being able to debug what’s going on under the hood, I don’t have any other suggestions at this time.

It’s possible you have more going on under the hood than we can determine here. Did you try going directly to /wp-admin when the theme folder was renamed? Do you have the default WordPress Twenty Fifteen theme in your folder?

Either way, since the theme thing didn’t work, I’d try the following:

Rename the folders of any plugins you have active, so that WordPress deactivates them. Then try going directly to /wp-admin and try to login.

Do you see any errors in the debug.log file inside your wp-content directory?

If you set it up as a post, you can have the URL structure contain the category by going to Settings > Permalinks and setting the custom structure to %category%/%postname%/.

Doing this though, you’ll want to only assign posts to one category to ensure the correct one gets used.

But, you’re left with the issue of using a specific template for that particular post. You can do this with a bit of custom code.

First, you need the post ID of this special post. You can get that by editing the post in the admin and looking at the post ID in the URL. http://cl.ly/image/0i1e3n0T293t Note the post=744. In this case, my post ID is 744.

Armed with this, you can create a template that’s made especially for that post. Normally a single post is displayed by the single.php template file. If you have another template, make a copy of it and name it single-744.php (replace 744 with your post ID).

Use this code to override the template for that special post.

function jp_single_template_id( $located_template ) {
	$single_template = locate_template( array( sprintf( "single-%d.php", absint( get_the_ID() ) ), $located_template ) );
	if( ! empty( $single_template ) ) {
		return $single_template;
	} else {
		return $located_template;
	}
}
add_filter( 'single_template', 'jp_single_template_id' );

This code will load that template for just that post, and fallback to the default template for all other posts.

Try setting ‘paged’ this way:

if ( get_query_var( 'paged' ) ) :
	$paged = get_query_var( 'paged' );
elseif ( get_query_var( 'page' ) ) :
	$paged = get_query_var( 'page' );
else :
	$paged = 1;
endif;

Also, as noted in the documentation, query_posts is not meant to be used like this. https://codex.ww.wp.xz.cn/Function_Reference/query_posts

See WP_Query instead. https://codex.ww.wp.xz.cn/Class_Reference/WP_Query

You can do something like this using the Connections Business Directory plugin.

Hi,

Pages can’t be assigned to categories by default. Posts can.

So, if you’re using pages, you set up a parent page called, for example, Checkout. Then you create another page and set the Parent page in the Page Attributes box. http://cl.ly/image/13400V3s3P0M

This would give you a URL of /checkout/pagename.
