I imported existing wordpress instances into workbench (wp staging testing instance was also imported as separate site). As i deleted staging instance in plugin, later tried to delete and Workbench site for testing site, it also deleted something from live site as it brake my main live website (i guess it was database - i imediatly restore backup, didnt have time to check).
Hello,
Are you certain about that? And does this actually occur, and can you reproduce it consistently?
