whitesceen on subsites

Hi, I had some problems with the host getting wildcardDNS to resolve which has now been sorted however I am since getting white-screen on the subsite pages and posts. Dashboards are OK.

Memory is a bit foggy but I don’t seem to have subsite directory’s within the host directory anywhere(wasn’t there a blogs directory). Is this the error or am I looking in the wrong place.

All these databases have been created and seem appropriately populated:

wp_blogs
wp_blog_versions
wp_registration_log
wp_signups
wp_site
wp_sitemeta

Apache error log shows nothing concerning this domain at all.

I have virtualenergy.co.uk installed here: /public_html/virtualenergy.co.uk

On all subsites (test,test2, and abods) all plugins deactivated and either twentyfourteen or twentyfifteen in place.

For the sake of brevity I have edited out the Authentication Unique Keys and Salts but otherwise here is the wp-config and .htaccess.
