My b2evolution Version: 1.10.2

Version 1.10.2 - been a bit lazy on versioning as the blog works so well normally. However...

When we create a new post and then click Preview, we are not getting the post content displayed. The post title, author details and permalink appear but not the post content(the body of the post).

Our existing posts display fine, but if you try to edit one, the same thing happens to them when you previw the change. No content.

I've looked in the database and the post content is in the database.

Might be a red herring, but etween our last successful post and now, our host has moved server.

Anyone have any thoughts?
