I have a 404 problem with pagination on topics archive pages, for both admins and non-admins. The first page display correctly, but get a 404 errors on subsequent pages:
I am using a custom `archive-topic.php` on my theme and using the following plugins on WordPress 3.5.1:
User Switching 0.7.1
WordPress Post Type Archive Links 1.1
WordPress SEO 1.4.4
I have disabled all plugins and switched the theme to TwentyTen with flushing rewrite rules on every steps with no success. I have also changed the permalink structure to default `?post_type=topic&paged=2` and still not working.
