Sincronization not picking anymore images from subfolders

[cristian.otobacu]

Hi,
I have  a strange situation. I have organized categories in subfolders in /images/stories/Virtuemart/categories. Everything was going well while doing "Sincronize Media to VirtueMart" or using DB Tools, mening that the images in subfolders were available when inserting into cathegories. Today suddenly the system only picks the image in the root folder and not the ones in subfolders. Virtuemart version in 2.0.26d.
Any sugentions?
Thanks
Cristian
