Mutisite plugin CLONER

Have created a Multisite and am using CLONER to create child sites – get a message An Error Has Occured after Settings Updated -(CLONER configured with ALL settings) & Cloned site is incomplete (Posts not all replicated and some settings).

Have cloned 5 sites successfully (NO ERRORS) and 4 have errors.

Is there a log-file or something else I need to do?
