I have imported the data from the demo (number 6) and I notice that the images do not appear.
For example, the image exists in the catalog (../wp-content/uploads/2019/05/top-view-portrait-exhausted-young-african-fitness-man-1060.jpg) but does not appear either during download or in browser.

When try to view on filemanager the above image, appear HTML document, ASCII text ‘One moment, please…
