      When I install ‘enable multi site’ it installs OK but then I lose
      all my options in the ‘Plugins’ menu. Cannot add new plugins
      or uninstall the ‘enable multi site plugin’ I have used multi sites
      on this domain for over a year until my site was hacked into last
      week and I lost all my multisites. I have had my hosting company reset my account twice already and it looks as if I will have to ask them again and then forget about multisites, unless you know of any other way to get my ‘Plugins’ menu back.

      Thank you
