Okay, found it already. Apparently with the update to Virtuemart 2.026D, a number of tables have been renamed in Virtuemart.
Therefore two areas in the virtuemart pluging need to be changed (/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/plugin/cbsubsvirtuemart/cbsubs.virtuemart.php")
lin 623-624:
Code:
. ', ' . $_CB_database->NameQuote( 'virtuemart_permgroup_id' ) . ' AS id'
"\n FROM " . $_CB_database->NameQuote( '#__virtuemart_permgroups' )
And line 680-681
Code:
. ', ' . $_CB_database->NameQuote( 'virtuemart_vendor_id' ) . ' AS id'
. "\n FROM " . $_CB_database->NameQuote( '#__virtuemart_vendors' )
