I'm a WordPress novice and I tried out duplicator. I saved a package, then used the package and the installer to clone my WordPress website at another place on my web host. All seems to have gone well except for one small thing:
I titled the new site "Carol's WordPress Clone" and in both the front end and back end the site title contained a backslash before the apostropne in Carol's.
I appear to have fixed the problem by logging into the clone's back end and removed the backslash from the site title.
Let me know if you have any questions. Your website says duplicator is in Beta test and you are seeking feedback. Here it is. The clone is currently at http://surfpix.net/wordpress.
