Error in product filter if i choose "filter on modified price"

[chabi01]

Hi,
I try to show only prices with modified price.
When i just select the option in the filter and click ok, i get this :

Code Select Expand

vmError: exeSortSearchListQuery Column 'created_on' in order clause is ambiguous SQL=SELECT SQL_CALC_FOUND_ROWS p.`virtuemart_product_id` FROM `j2hvs_virtuemart_products` as p INNER JOIN `j2hvs_virtuemart_products_fr_fr` as l using (`virtuemart_product_id`) LEFT JOIN `j2hvs_virtuemart_product_prices` as pp ON p.`virtuemart_product_id` = pp.`virtuemart_product_id` WHERE (pp.`modified_on` < "15:27 15.12.2014") group by p.`virtuemart_product_id` ORDER BY created_on DESC LIMIT 0, 20
[/code]
I use VM 2.6.4.
I have allready tried to correct the table with the VM Tools...without success.

If there is any solution..
Thanks

VM2.6.4 is quite old and known to be insecure so updating to current VM2.6.14 is recommended. I have 2.6.14 and do not see the error.
