Virtuemart 2.02 not working on frontend

So situation is that when you keep ON the SEO on the frontend of Virtuemart 2.0.22c the editing/saving doesn't work, it takes back to the home page without saving nothing.
when i off the SEO it works correctly...

the problem now is that i don't want to off the SEO (First) and i don't want that on the url is writting all the path instead of the alias menu...

EXAMPLE: index.php?option=com_virtuemart&view=category&virtuemart_category_id=28&Itemid=275&lang=it

how can i solve it? still you think something from the template? in anycase i will renew for one year member.

thank you

Did you update template?

i just made the payment for 12 months membership... i downloaded the new template, what exactly i should update?

thank you

OK NEWS: i added new templates completly and no changes, am not able to edit virtuemart from frontend if sef IS ON...

thank you

Latest template is compatible with latest vm, so that means there is some issue with something else. But since it is not template issue you can pay us custom job so we fix it.

pay to customize what?

i just added your templates 100% without no changing, i on SEF and virtuemart don't work from frontend... and i tested it on more than one template, all of them has same problem, when is on SEF is not possible to edit from backend. i don't think is something to customize more than to FIX

thank you
