Hello,
I've been developing my site on a subdomain of my own website e.g. http://test.my-domain.com however when i've moved this over to the my clients live domain, which is different polylang breaks and the site just goes to a server 404 page.
I've changed the site url in the wp_options table and the admin works fine. If i deactivate polylang again the site works, but if i reactivate it breaks. I've tried resaving polylang settings, but to no avail. Please can someone help or point me in the right direction?
