I have been trying to move/copy an elgg install to a different hosting provider.  So far I have had less than ideal results.  I didn't find the http://docs.elgg.org/wiki/DuplicateInstallation page until after I started. But I think I have followed it more or less by editing the SQL backup of the elgg database.

 I will start over this afternoon and try to follow the instructions directly.  However the issue I had was that it seemed ALL plugins/modules/widgets were disabled.   Does that ring any bells with elgg experts?

Thanks!  I will post my findings.
