Hi Chuck, thanks for confirming of what I've already checked many times. Strange thing is, no one has changed anything, and then one day it does this.
I tried posting without uploading a photo and FTPing a jpg to the site ("bypass approval process and upload all files in directory"). That way, it works. But uploading "From my Computer" brings on the errors.
I'm still puzzled by the following statement, it makes me believe this is a Server provider problem.
