I'm getting some help from a developer for the blog part of my site and also converting the static pages to use WordPress as a CMS. I'm trying to understand how this works in order to complete the move myself and to ensure that everything is set up correctly - after we had some problems with the setup on the server.
I'm getting confused about the way that it is supposed to work - particularly because there are separate themes for the main site and the blog.
After the initial problems on the server, the developer set it up so that the switch between the blog and the regular site is done with hard coded URLs to include the theme, thus http://www.website.com/wordpress_test/index.php?wptheme=site+blog from regular to blog and http://www.website.com/wordpress_test/index.php?wptheme=site. The developer says that this is only temporary, and that two separate WordPress instances are needed to do it properly.
I'm going a bit nuts trying to test it out and prepare for the move, so wanted to check if this approach is correct. As I understand it, I'm eventually supposed to have www.website.com\wordpress_test\ which has a WordPress instance - including the site theme - and then www.website.com\wordpress_test\blog with another WordPress instance and theme.
Is this correct? Does it make sense to the experts?
Thanks!
