Ok, I think I got it now. Sorry for being so dense. I was using an older version of Safari and when I was selecting the upload icon, it wasn't bringing up the popup to select a file. It works when I use Chrome.
I tried uploading an AIML file that I copied from Pandorabots and that works there, but when I try to upload it I get this error message:
Parsing error occurred - org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.
I'm not a very good programmer, so I don't want to take up too much of your time. I was just trying to see if I could use the BOT Libre platform to create some storyteller bots like the ones I created on Pandorabots. I wanted to see what the difference in the platforms would be.
