Configuring MALLET for Omeka Classic - Text Analysis Plugin

I’m trying to configure the Text Analysis plugin for my Omeka site. To use the plugin it needs to be configured to connect to an IBM account and a MALLET script directory. I think I configured the IBM stuff correctly, but when I try to include the path to the MALLET directory I get this error:

“The MALLET script directory is invalid. Make sure the directory contains the MALLET script and that the script is executable by the web server.”

So far I’ve tried this using these file paths:


Any idea what I’m doing wrong or misunderstanding?
