    Description

      Steps:

      • Have a 7.0 instance running on port 8080.
        • Not sure if relevant but: on this instance I've made changes on Flamingo skin + on various changes to FlamingoThemes on both main wiki and subwiki.
      • I've opened another 7.0 instance on port 8084.
        • No problem at starting
        • Closed it
      • I've reopened the 8084 instance after a while and I got browser.png
