and thank you Sifur for your help so far.
I am very familiar with Hikashop, I have used it for years, however, when adding an image to a product I have a problem.
The image uploads to images/com_hikashop/upload, I see it there ..
all folder and image permissions are 755 except the new one I uploaded which is 644,
I change this top 755 but nothing.
So, I deleted all hikashop generated folders, this allows hikashop to regenerate all existing image thumbnails again.
the folders regenerated but now no product images at all are showing.
Can you please advise?
