Hello,
value virtuemart_vendor_id #__virtuemart_customs table
what do you mean by field? where do i find this? is that in the template or options? or under VM > configurations?
#__virtuemart_customs is a VirtueMart table and you need to look for it in your database. Use the tool with which you access you site database and look for #__virtuemart_customs table in the list(#_ will be your table prefix). In that table records check for rows with entries as "Related Products" and "Related Categories" in custom_title column. For these rows check column
virtuemart_vendor_id and change its value to 0 if its entered as 1 and that will solve your issue. Hope it is clear now.
Kind regards,
Tharuna
