 * Hi
 * I installed the free plugin simple:press on my wordpress site and i got the following
   Message: “Das Plugin erzeugte 167 Zeichen mit unerwarteter Ausgabe während der
   Aktivierung. Wenn du „headers already sent“-Hinweise, Probleme mit Syndication-
   Feeds oder andere Probleme bemerkst, versuche, dieses Plugin zu deaktivieren 
   oder zu entfernen.”
    In english : “The plugin generated 167 characters with an
   unexpected output during activation. If you have “headers already sent”- hints,
   problems with syndication feeds or other problems, try to deactivate or remove
   this Plugin.”
 * Additionally there is the Text: “Warning: Creating default object from empty 
   value in /home/httpd/vhosts/akustika.ch/httpdocs/wp-content/plugins/simplepress/
   sp-api/sp-api-class-spcdb.php on line 552 ” on the very top of every page. Frontend
   and backend.
 * The plugin also messed up my row heights somehow but i was able to fix that issue.
 * I just installed the latest version 6.5.1 and i don’t have any plugins or themes
   for simple:press installed.
 * Do i need to worry about these issues and how can i get rid ot the warning on
   every page?

 * Hi:
 * If you’re seeing a ‘headers already sent’, its likely going to be because of 
   a conflict with another plugin or the WordPress theme that is installed.
 * You said it showed up during activation. Has it shown up after that?
 * The reason errors show up on the front-end is because you have your debug options
   in wp-config.php set to display errors there. Normally, they should only go to
   the debug.log file. Once you’re done debugging issues you should probably turn
   the display option off.

 * Sorry on getting back onto this topic but I have experienced the same problem.
   I have realized that after deactivating the simple Press plugin the error goes
   away so it is the actual Simple Press plugin throwing the error.
 * Do you have any advice on how to fix this.
