1054 - Unknown column 'a.custom_value' in 'field list'

[limbotron]

Hi, my problem is: "1054 - Unknown column 'a.custom_value' in 'field list'"
after upgrade VM2 to VM3.
My "#__virtuemart_customs" table column is:
custom_desc
AND table "#__virtuemart_product_customfields" column is:
customfield_value
customfield_price
customfield_params

What is wrong?
Thanks in advance

You use a product customfield plugin ?

[limbotron]

I use "Custom Fields for All" plugin.

The next question is whether you've updated the "Custom Fields for All" plugin? 

[limbotron]

No. I use v1.6. and i don't know how to update automatically

[limbotron]

I found solution.
Need change "a.custom_value" to "a.customfield_value"
In \templates\theme_name\html\com_virtuemart\category\name-category.php file
