Setting up the Admin account for you, led me to the source of the problem. I created the admin account but wanted to test it before I sent the details. Odd thing was, the problem didn't show up with the account I setup for you.
So, what was the difference.
My upload folder is at /uploads/MyUserID/
Your upload folder was at /uploads/YourUserID/
My folder had 7 or 8 large image files (for some reason). I think they were residual files that were left in that folder, for some reason I'm not sure about. Anyway, I assume that is a temporary folder for the initial upload, before moving to the category folder. When the bulkupload.php script executes, it thinks all those images are to be uploaded and the program crashes, for some reason (probably my upload limit or something); although my admin account has no limits. AND, the files are already uploaded (from previous uploads using FTP) so it can't be a PHP upload limit.
Anyway, I cleared out all those images from the /uploads/MyUserID/ folder and my problems went away.
Is the /uploads/MyUserID/ folder supposed to be cleared out after each upload? What can cause the images to remain?
OH Wait! I just realized that I might have used that to upload some images by FTPing them to that folder and using a URL for the upload. I had that feature to leave the files in the folder. OOPS! I probably should not have checked the "do not delete" files from the upload folder. But that folder seems to be a default. Should one normally use a different folder for FTP uploads?
Have I sized up this problem correctly? Anyway, it seems to have worked. I just need to understand the usage of the /uploads/MyUserID/ folder.
