Please test if this worked.

Is it OK if i upload next week? The point is that testing one image in practice equals preparing the whole upload. I just got the final metadata and massaging them for GWToolset, perhaps adjusting translations etc.. can take a few working days.

This procedure of whitelisting has worked excellently with me say 10 times ever since May 2014, thanks to you guys (testing was never necessary, it is a new feature). So i trust it works this time as well. Best regards, Hansmuller

PS It's probably my own fault (forgot to set the security?), but it seems better if domains and paths are not publicly divulged. Can this be repaired? Thank you, Hansmuller

Yes, sure. The domain will remain whitelisted as long it'll be possible so you can upload it anytime you want.

Usually the one who prepared the patch (in this case, me) should test if it works. But I have no access to GWToolset so I can't test it. That's the reason why we asked you if you can test it.

Why do you want to move the domain to private settings? The file with settings (and whitelisted domains) is publicly visible and I can't find out any reason why this domain shouldn't be visible now. Thanks for your reply.

The private settings files are for passwords, this won't be moved there.

@Krenair I know but there must be some reason why Hans requested hiding this. So I asked for it :).
