Failed to load plugin

Hi, I am getting the above error in my editor, just after I installed your plugin. In addition it gives me a very long list of extra values (slightly changed to remove the site identifying details):

<site-path> is the local path to the location of the site.
<site-url> is the domain for this website.

In my Inspector, I also get a bunch of javascript errors, related to this issue.

I was so far unable to use the plugin at all, but it looks like it is closest I could find to simply share a folder from Dropbox with viewers to the specific website.

I am a web developer and as such can perform advanced debugging, just need guidance as to how your plugin works.

PS: There are a few non-English words in the plugin (so far I have seen the tabs of the settings page as well as the sections in the settings pages).
