Thanks for the hint, I have check the chmod both folders there are already full writeable 777. Also the folder com_export_content is 777. Try again, but result remain the same.
What version are you compiling for 1.0+ or 1.5+?
And how are you compiling by sections or static content items?
If by sections are you including static and or archived items?
Do the "download" and "remove all" icons appear at the top after you press "compile"?
