I ended having to load the site using IE11 in order to duplicate it. The difference ended up being access the site via http://limabuildingtrades.com vs http://www.limabuildingtrades.com. Notice the www
you have your site configured to require the www
so when you access the site without it, WP tries to do the redirect internally to prevent duplicate content issues for search engines. You should set up this redirect in your htaccess. Using WP to handle the redirect causes unnecessary server load and just as importantly, slightly increase page load time.
That said… Connections does have a redirect which is only in effect when accessing the site’s frontpage. In simple terms the redirect is prevented. This is done to permit those who wish to use the directory on their sites frontpage to do so. Without this special case it would not be possible, for example, to view the single entry profile/detail view (not used in Slim Plus). What would occur is that WP assumes the user is trying to view a post instead of a directory entry which of course it will not find and display a 404 not found error. Basically it is the only way for plugins (not just Connections) shortcode to work on the front page when their shortcode relies on a query variable to determine what to display. Hope that is not confusing!
Any way, that said… I made the logic a little bit smarter. Please try again, should work fine. Let me know.
