I'm attempting to migrate our wordpress blog from blog.ourdomain.co.uk to ourdomain.co.uk/journal, but ourdomain.co.uk/journal always shows the content from ourdomain.co.uk/.

To keep the migration simple, I started with a blank wordpress install in /journal, then imported 'All Content' using WP's built in export/import features.

All seemed well at first, but when I visit ourdomain.co.uk/journal it does not show a wordpress home page, but instead the home page of our main site. Even visiting ourdomain.co.uk/journal/index.php results in this behaviour. This site issues a 301 to redirect to ourdomain.co.uk/journal, and then I see the main site homepage rather than wordpress.

I can't see anything in the parent directory .htaccess file which would make this happen. The wordpress .htaccess file contains the code as per below, most of which was auto-created by wordpress, but I added the wp-admin redirect rule.

I can visit and use https://www.ourdomain.co.uk/journal/wp-admin/ no problem. Database cxn is OK. I can also visit static files such as https://www.ourdomain.co.uk/journal/readme.html. Links direct to posts also work fine, such as https://www.ourdomain.co.uk/journal/2021/post-title-here/ - it's just the homepage.

Even if I set the home page to be a static page, such as our about page in wordpress, this still happens.

I have defined define('WP_HOME', 'https://www.ourdomain.co.uk/journal'); and define('WP_SITEURL', 'https://www.ourdomain.co.uk/journal'); in wp-config.php

If I delete the contents of the /journal .htaccess file, then I am able to load https://www.ourdomain.co.uk/journal ONCE, then it goes wrong again because wordpress has rewritten the rewrite code to .htaccess - so clearly this is something to do with permalinks, but I'm unable to figure out what, exactly, the deal is.

Any help gratefully received.
