Thread:Support/Problem when pressing "Save and open next"

I have a problem whit the "Save and open next" button, every time I press it( or the alt-s shortcut) I get send to "http://translatewiki.net/w/api.php" whit in his case the text:

{"edit":{"new":"","result":"Success","pageid":2151899,"title":"FUDforum:Month 11\/da","oldrevid":0,"newrevid":3084935,"newtimestamp":"2011-06-13T19:22:33Z"}}

Any idea what might be causing this?
