Probably upgrade.php isn't uploading properly. Who's your host? What FTP Client do you use?
I'm on a VPS, and I'm using FileZilla. I also tried Transmit, but no luck.
Hi,
Can you reupload all your files. Check the last modified dates to make sure they show up as the new ones.
Let us know if it's still blank. I think the next step, if it's still blank, would be to ask your host to check to see if it's generating errors but hiding them.
Thanks,
Ryan
Well, it works now. I'm not sure how I fixed it though.
Well, we are glad to see this has been fixed
