 * Can’t post any new or edited entries anymore.
    If I deactivate this plugins, 
   everything works fine.
 * Error-Text:
    “Das Plugin verursachte 4 Zeichen unerwartete Ausgabe während der
   Aktivierung. Solltest du Fehlermeldungen wie „headers already sent“, Probleme
   mit der Syndizierung der Feeds oder andere Fehler erhalten, versuche, das Plugin

 * it appears there is an “var_” on the first line of the function.php for this 
   new update (4.3.2)
 * We have removed that, and it went back to working normally 🙂
 * to edit it, go to PLUGINS > find WP Slimstat Analytics > click on EDIT under 
   it > edit the wp-slimstat/wp-slimstat.php file (by removing the “var_” right 
   on the beginning of the file
 * Hope this helps 🙂

 * Hi,
 * thank you UP3 for providing a temporary workaround, much appreciated. Version
   4.3.2.1 should take care of the problem. Please let us know if that’s the case.
 * Best,
    Jason
