when activating User Synch, the site went down and white page.

I have to delete the User Synch from FTP to login the site.

Now in your data base site1.ca is still in using this plugin. But actually it no longer using it.

When I trying to install User Synch on test sites: en.testsite.com and cn.testsite.com, it jumps back and forth between your site and my dashboard. it's no longer like the experience when installing the first in site1.ca.

Please check.
