upload ok but popup is loading until the upload finishes

[kenwaz]

Hello,
I'm using the free version of xuppload under an ubuntu server whith apache 2.

I followed the instructions to install the app , but the popup remains blank (loading) until the upload is finished. Then I have the popup showing "upload complete" with the avg speed.. And the main main window is redirected to post.php and can the informations of the file.
So it does work but I would like the progress bar popup updated regularly.

I tried to reinstall from scratch, but same result.

Any clue ?

Thank you
