I did two 1P ranges for GFN17 running on AMD cards under Windows 7 (64 bit), but when I try to upload the files, I get the error in the thread title. What's the problem? Do I need the checkpoint files as well?

The cards are Radeon HD 5770 and HD 6450, the latter with a mild core overclock. When I started the executables, I also got this message in the command prompt: "warning: #warning directive: No built-in carry flag support known, using plain C code", though both ran to conclusion.

EDIT: k, posted too soon, it would seem. Looks like the problem was me moving the files to another computer and trying to upload them from there. It worked when I did it from the original host.

I had the same problem trying to upload through a VPN, that changed the referer.
Solution : direct connection without VPN.

What's this referer value that's wrong? It's only used to try to get you back to the same page you were on before you started interacting with the sieving system (making a reservation or uploading a file). Remember, if all else fails you can always email the file to me (email address is on the Contacts page - link is at the very bottom of your screen).

Any referer failure after an upload should be harmless in that the upload already happened. But if I'm wrong about that, please let me know.

I will do some more tests this evening (Europe time), so expect several small reservations. I will post the results afterwards.

I tested the following, on f21_210385P_210386P :

- Upload using Chrome with PureVPN extension active (masqueraded IP etc) => fails with message "missing or bad parameter: referer"
- Upload using Chrome with PureVPN extension disconnected (NATed IP from my home connection) => uploads file correctly.
- EDIT : also tried yesterday with Firefox without VPN => works fine

That's probably due to the php upload script getting confused by the VPN. No big deal, I just have to remember to turn it off before uploading.
This post is mostly for the record, in case someone else falls in the same trap.

- Upload using Chrome with PureVPN extension active (masqueraded IP etc) => fails with message "missing or bad parameter: referer"

I think that problem is not in VPN itself but in this specific browser extension which also strips "Referrer" header for extra anonymity. May it could be turned of in extension' setting.

Well, referer is only used for convinience, a conviniece thing shouldn't throw an error.

I assume the code in php is using $_SERVER['HTTP_REFERER']. You should just check

I tracked this down - it was an error in my code. In one place referer was treated as mandatory. I've changed the parameter on a function call to show that it's optional and this bug should now be killed.
