Hosts moved server set up, now have issues

Hi, Our hosts just moved our site to a completely different server. They just 'moved' it all over and told us it had happened and now we are getting a server 500 error when trying to create new pages or blog posts. I thought this would be a permissions error but can't see anything wrong with the permissions or the owner/group of the files. I need to go to the hosts to get them to fix whatever is now broken but not entirely sure what I should be telling them to do (apart from not move our site without notifying us!). Can you see from the diagnostics report below what it could be
