I have just found a problem between WP-Trader and seo-wordpress. I have tried to sort it myself but cannot figure it out. In WP-Trader when wordpress-seo is enabled all pages are blank. As soon as I disable wordpress-seo the pages show as they are supposed to.
I have went through wordpress-seo disabling features to try and pinpoint what was causing it but had no luck at all. Hopefully somebody here can help as both plugins are pretty important to this upcoming project.
