[Plugin: Facebook Event List Shortcode] doesn't work with all hosts

This plugin worked great for me on one site, but on another host, not at all.
Due to a message I got while testing another plugin, I suspect it is because I do not have permission to access /wp-content/plugins/tinymce/ on the server.
Anyway I am getting a support ticket on it to see if it can be resolved. If not, I can move the site.
Just wanted to put this out there.
