Upload is not working after upgrade V4.0.1

I would be tempted to upload the theme files again making sure you upload them in binary mode.

re-install the script and make backups before editing anything.

I have the same problem with a clean install (just purchased yesterday) on a brand new server running Centos 6.6
I'm going to try it on a slightly older server.

I've now tried it on a different server, a shared server hosting over 30 other sites but the problem is as before; when clicking "Upload", the screen dims slightly but the "Drag & drop files here or click to browse... " pop up doesn't pop up! Is the Demo on yetishre.com 4.01?

Has anybody else had the "Drag & drop files here or click to browse... " not appearing when clicking "Upload" after installing ver.4.01?

Edit

Line 28
Change to
Your domain WITHOUT the http://www, section. ONLY domain.com

We're working on a fix for the next version.

Many thanks to Adam for his help with this last night.

Many thanks. I did an off-line support request last night and Adam replied very quickly and gave me a similar answer.
Many thanks once again.
