I'm trying to upload some pics showing some heavy CA for advice from forum members. I keep getting an "upload failed-check file size" even though the jpgs are well under the max file size.
Very rarely, upload folders become corrupted when you first try to upload a file and thus prevent you from upload anything until else I rebuild the folder in the filesystem. I will have a look at that now and I'll get back to you shortly.
I just checked the filesystem and it doesn't look like you're attempted at making any uploads. Are you using the attachment system or the user photo gallery?
