 * Hello, I have a wordpress MU with several sites in subdirectories (Debian 10 
   server / IspConfig)
 * I have a site that has changed domain (WPMU/old.domain.com). I cloned it inside
   the network > WPMU/new.domain.com
 * The new site indicated that there were several 302 and 301 redirects.
 * I wanted to use your plugin to search for all occurrences of “old.domain.com”
   to replace them with “new.domain.com”.
 * The plugin found a lot of them and maybe too many.
 * As a result, no site works anymore and returns 404 errors everywhere.
 * I think this plugin is not adapted to multi-site.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fon-multisite-crashed-everything%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
