Which version of Magento and PHP are you using?
Can you provide more details? (it seems the layout object has some problem)
it is magento 1.9.3 and php 5.6
it has been moved from another server, I adapted the settings in the database for the new url, is there another place where the location of the layout needs to be configured?
Normally you shouldn't need anything extra.
Maybe there is a problem with CMS pages or blocks?
Can you try with RWD just to start to look if the problem is at module level or theme or maybe at some other level?
