I'm using it with Virtuemart 3.0.9 and Joomla 3.4.3.
If I try to export/import Virtuemart product all works correctly using standard fields (product_name, product_sku etc...), but when I try to export/import using "Custom Field" Fields ("custom_title";"custom_value";"custom_param"

In the second image attached is shown Option tab of Export Template.
My Export/Import templates are Component -> Virtuemart and Operation -> Product
I installed correctly plg_csviext_param_csvi_6.0rc1 and plg_csviaddon_customfilters_csvi_6.0rc1 and I've published it.
I've also tried to Update Field in Avaible Fields (Maintenance) before export/import.
I've also correctly bought and installed "Virtuemart 2 Product Filter by Custom Fields" for Joomla 3.
I created the Custom Field correctly using this guide.
I use CSVI with Joomla 2.5 since 2 years importing custom field values without problem, but with CSVI 6 I receive there errors using the same configuration and settings
How can I solve this errors? Thanks
