[Plugin: AskApache Password Protect] Help! Broken AAPro plugin & Wp-admin

I love this plugin. Perhaps someone could help me fix it? Here is exactly how the problem occurred. (Note that WP-admin ‘works’ but is all in text now- see below).

After upgrading to WP 2.6, I upgraded to 4.3.2. Before doing anything else I went to the AAPro settings and saw that all settings said “Success” except for plain encryption. I clicked on the Update settings button (or whatever the button is on that page) and got the AAPro password prompt that Ive seen dozens of time. I entered in the username and password that I always have..and it wouldnt work!! Then I tried to refresh WP-admin and I got the password prompt again, hitting cancel this time and got an “Internal Server Error.”

Are there instructions on how to properly clean your WP directories of AAPro and start over?

I have no idea so what I did was remove the AAPro plugin folder from my plugins directory. I still couldnt get into WP because I still saw the password prompt. So I went to wp-admin ht-access and removed the AAPro section. This got me back into WP-admin without the prompt.

So I manually install a fresh AAPro plugin 4.3.2 from my cpanel. Activate it. Go to the AAPro settings and see the same settings as I did before. All successful except one. I click that change settings button below all of that and it takes me to the next page. I see that the default user is admin and password is blank (would entering this initially have averted this disaster?) I type in the same user and pass that I always have and click ‘change password.’ The page reloads with the internal server error again.

So I go straight to wp-admin in cpanel and remove the AAPro content and refresh wp-admin. Now wp-admin in firefox is all text-based. Everything looks like black and white 1995 html internet. Links and functionality are still there. But wp-admin is normal in other browsers! I have disabled the AAPro plugin as a result of all of this.

How do I fix my files so that AAPro works again?
