Why won't my Web Tender setting save?

[SvenR]

Hi,

run into problem that for some reason my Web Tender doesn’t work right. I‘m able to pull in the order via web tender but when process it I get the error „unable to process web orders,as your defined web tender 0 does not exist“ . I have then try rmsify-settings-tender settings and select WEB TENDER-Ok but it will not safe that setting . So I’m pretty sure that’s the issue… but why will it not Save the Web Tender?? Help please. Thanks
