Seem to be having the same problem. Removing
header(‘Content-Length: ‘ . filesize($file));
Did not work.
Strange thing is I just installed Zip attachements on a different domain (different theme) but I am getting the same error. I am wondering if its a recent wordpress update.
Where should the file normally be generated and I will try to play with permissions.
This used to work on a previous site but since we installed a new theme it stopped working.
Anyway thanks for your help.
Hi Ricard,
Have a look at: http://3.cheappropertybansko.com/properties/luxurious-furnished-studio-on-pirin-golf/
Let me know when you see it as this is a testing server which I need to take offline.
Many thanks
