I have a local development server and a live site. Duplicator worked perfectly up through wp ver 3.7.1. After updating to wp ver 3.8 it is not working correctly. Duplicator creates the zip file and installer as usual. When I try to have it install on the live server, everything appears to work until I attempt to access the site. It dies with “INTERNAL SERVER ERROR”. Both servers are RHEL 6 based. I have been working on this for two days.
