Problem with a ShadedGrey Theme

Where is your WP install? in …/blog or …/wordpress?
And if you want the install and the display in different directories, did you follow any of the guides for that?
e.g. https://www.ads-software.com/docs/installation/different-address/

The WP install is in /wordpress and the content should be in /blog. I followed all the steps:

My index.php says:

<?php
/* Short and sweet */
define(‘WP_USE_THEMES’, true);
require(‘./wordpress/wp-blog-header.php’);
?>

require('./wordpress/wp-blog-header.php');

if the two folders (blog and wordpress) are on the same level, i.e. wordpress is NOT under blog, than the above code line is not correct…

So, what should the correct code be, then? Both /blog and /wordpress are subdirectories of the root.

Can anyone help with this? The ShadedGrey theme works in the /wordpress subdirectory but I need it to work in the /blog subdirectory which has been assigned to be the URL for the blog.

Thanks in advance,
Mitko

Try if this works:
require('../wordpress/wp-blog-header.php');

Nothing changed:
When you go to https://www.websage.net/wordpress/ it works; when you go to:
https://www.websage.net/blog/ I get the following error:

Warning: main(./wp-blog-header.php): failed to open stream: No such file or directory in /home/websagen/public_html/wordpress/wp-content/themes/ShadedGrey/index.php on line 3

Warning: main(./wp-blog-header.php): failed to open stream: No such file or directory in /home/websagen/public_html/wordpress/wp-content/themes/ShadedGrey/index.php on line 3

Fatal error: main(): Failed opening required ‘./wp-blog-header.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/websagen/public_html/wordpress/wp-content/themes/ShadedGrey/index.php on line 3

From my admin’s options:

WordPress address (URI): https://websage.net/wordpress
Blog address (URI): https://websage.net/blog

Take a second look to what I posted above and change it in the so-called sweet and short index.
Or copy from here!
It wasn’t ./ but ../

And since this is not a WP specific question, it is time to learn about relative path (try Google)

OK, sorry, I was confused about which index should I change — the one in wordpress/index.php (this is where I put require(‘../wordpress/wp-blog-header.php’);
or the one in /wp-content/themes/ShadedGrey…

Thanks, it all works now!

Your confusion might be caused by not reading what I posted earlier. But glad it works now.
