error 1054 on display category

[Xakart]

I deleted categories and created new and now when I go into any virtuemart  category I see this error

1054
Unknown column 'searchable' in 'where clause' SQL=SELECT c.* FROM #__virtuemart_customs as c INNER JOIN #__virtuemart_product_customfields as pc on (c.virtuemart_custom_id=pc.virtuemart_custom_id) INNER JOIN #__virtuemart_product_categories as cat ON (pc.virtuemart_product_id=cat.virtuemart_product_id) WHERE virtuemart_category_id="20" and searchable="1" and (field_type="S" or field_type="P") GROUP BY c.virtuemart_custom_id

I am a rookie and this is my first job, I'm studying to be an application developer and now I do not have much knowledge

As  a beginner you would do your self a service by learning to search for information..
