I don't understand why it no longer makes me upload merchant logos via admin page? Also is there another way to upload them? The error it gives me is: "Image Filename".
the logo is a jpg and like all the others that I have already uploaded.
I did not understand what could be that from the Admin panel but by inserting the logo with the exact name of the merchant it works fine!
I know you have been using the script for several years, in earlier distributions the logo files were just an exact match of the merchant name.
If uploading through /admin/ the filename on your local computer shouldn't matter as it automatically saves the image with the extension configured in config.advanced.php at line 96:
$config_logoExtension = ".img";
If uploading manually to the /logos/ folder, the filenames must exactly match the merchant name (including spaces) with the above extension e.g.
