Topic: Release 2.3.9. Please update to this.
Due to some nasty bugs in release 2.3.8 regarding output buffering and incompatible static Session Manager you are kindly asked to update to release 2.3.9.
The package is located at Sourceforge .
This is very simple. Just overwrite your existing 2.3.7 or 2.3.8 installation and you are done.
