How to display URL for categories?

[FranzFromFar]

Hello!
That's my first post, and... I'm Italian, so forgive me for my bad english 
first of all I've a problem with SEF alias "vmError: VmTableData Sef Alias in record is missing! Can't save the record with no Sef Alias" but I've read that is related to an out-of-date php version (mine in 6.2.17 or something similar) so I've requested to the hosting the update of php at least at 5.3 version.
But I've another problem, and I don't know if it's related to the question just described, I have not a url for every category but only for subcategory.
For example, if I click on a category, in the URL it's only displayed "shop" (in italian "negozio") and not "clothes", but if I click on a subcategory it's correctly displayed "Men clothes"...
What's going on? How can I resolve? I home someone can help me... I'm sure it's not a hard question but surely there's something I'm missing...
Ps excuse me for my bad english... I hope it's all comprehensible 
Thanks a lot, peace!

Hmmm -- struggling to understand..     but...

Is the category with "negozio" your top category and the name of the root VM menu item?

If so what do you want to see there?

But as always->  http://forum.virtuemart.net/index.php?topic=104795.0

and if you don't supply a live url you will get very few answers -
