Cannot Save product categories in Greek

[mikelamar]

Hello guys, I'm new user of virtuemart and came across with a strange problem.

Im using joomla 1.5.25(greek language for both front and backend) and VM 2.0.2
I downloader and installed VM 2.0.2 version  from http://dev.virtuemart.net/projects/virtuemart/files and greek language files
and then I tried to add a Product Category in Greek language but it couldn't be saved.
I took the following error:vmError: VmTableData Sef Alias in record is missing ! Can't save the record with no Sef Alias.
Then I tried in english and there was no such a problem.

Is there something Im doing wrong,any suggestions,solutions?

Hi

Check if you have filled-in the alias field. Maybe it cannot auto-generate aliases for non latin chars
