You try to save settings from SEO, PRO page and you get an error message from WordPress or you’re redirected to a 404 page?
It’s probably because your webhost doesn’t allow .htaccess editing from the WordPress admin.
To solve this, add this snippet to your wp-config.php
file (backup it first):
define('SEOPRESS_BLOCK_HTACCESS', true);
Save changes.
You should now be able to save SEOPress PRO settings without any issue!
