I'm really stuck here, and compounding errors with errors trying to track this down. I cannot get my catalogue to show at all, there appears to be no connection between the catalogue and the index page. or any other page not in admin. I have tried all the fixes related to this problem suggested in this thread, but no effect.

I have messed around with path settings in config.php files, sites_switch.php and site_config.php, but cannot crack it.
