 * Since yesterday night I get a “500 Internal Server Error” when trying to access
   my wordpress page (backend still working). After deaktivating Newsletter-Plugin
   the problem was solved.
    Then I updated the plugin, but I can not activate it:
   I directly get a screen with the “Internal Server Error”. The plugin is then 
   NOT activated, but backend and page works fine. Debug mode of wordpress did not
   show any Newsletter-errors. I also use qtranslate on that blog.

 * 500 error code should be logged on the apache error log. Can you check it?

 * Hi, it seems an out of memory error. Check the WP_MEMORY_LIMIT in your wp-config.
   php, if present.
