Permalink Problem

Hi,

this problem may not be theme related but I hope you can help me nevertheless. Two sites just changed their permalinks in the following way:

http://www.eiweisspulver-test.com/whey-protein/esn-designer-whey to http://www.eiweisspulver-test.com/whey-protein/esn-designer-whey-3
http://www.eiweisspulver-test.com/casein/esn-micellar-casein to http://www.eiweisspulver-test.com/casein/esn-micellar-casein-3

I think this happened after updating them. It is possible to change the permalinks but not to original url. It seems like there are already sites with these urls. If you visit these urls there is only one image on them. These sites are not listed under “sites” and the trash is empty.

Can you tell how to change the urls back?

Best regards,

Arkadi
