My b2evolution Version: 1.9.x

Hi,

due to a restore of an older backup some of my registered user names are gone. When I now try to display comments created by these users I only do get an error message saying that the username does not exist.

Because of that also the comment RSS feed is broken (as this message does appear there also).

And I cannot even edit these comments anymore because I only get the same error.

Any idea what I can do here? Is this a normal behaviour? Or is this a bug (that is what I assume...)?

Thanks,
Michael
