I am sure the problem I am having is not to do with duplicator but presumably the environment but wondering if anyone can shed any light on the whys of this scenario. Duplicating using Duplicator, to a local development stage, and cant get the home page to display. Turned on the wp-config: WP_DEBUG = true. Showing an error with a plugin, removed the plugin and a large wad of errors with other plugins detailed. Remove all the plugins and of course it works. But the question is more general than which plugins are the issue. The question is what would make the issues kill the local install but be ignored on the production hosted site.
I turned on DEBUG on the hosted site as well but wordpress displays only momentarily debug output - and then it appears to redirect displaying page with a link to the document 'Debugging in WordPress' on the WP Support pages.
Any pointers appreciated!
