      Description

      I regularly have errors that say "There was an error communicating with the server, status: 500". I'm using IE 11 and mysql (no addon, no other config).

      Examples of situations I got this error:

      • When I close the permalink popup
      • When I click the icons from the infoview

      It seems to be linked with this stacktrace:
