Plugin's tabs all have same line; no description, no extensions, no faq

Hello,
I read about this plugin a day or two ago here on the repository and decided to install it today.

When I originally read the various tabs, there was a lot of information available. Now, all tabs except for a couple have the same line:

“With this plugin you can create a “modal” link to open post/page and even login/logout and register form in modal window.”

I wonder if the information all got wiped out in an update? Note that I tried two different browsers and got the same results.

Wayback Machine has only archived some of the pages for the plugin on one date, and it’s pretty clear that information (i.e. exact implementation of the shortcode) is out of date.
Really long URL here

I’d like to try the plugin on my test site, but obviously need all of the information, and possibly a couple of the extensions.

Thanks
