15,102 Pointsdelete_content not deleting
I have this
delete "/:title" do
delete_content(params[:title])
redirect "/"
end

Treehouse TeacherOK. With the log and your full code, I was able to figure it out.
The first clue is this in the log:
"DELETE / HTTP/1.1"
It's sending a delete request to a path of /, rather than the correct path of /John%20Doe. Since there's no delete "/" route defined (only delete "/:title" is defined), you get a 404 (resource not found) response.
So why is it sending the delete request to / and not (e.g.) /John%20Doe? If you preview the app, bring up the "show" page, and right-click the delete button, you'll see this HTML code for the form:
<form method="post" action="/">
And why does does the action attribute have an incomplete path? Well, the code to set up that link is in show.erb:
<form method="post" action="/<% @title %>">
And there's the problem. <% @title %> evaluates to the page title, but then does nothing with it. To insert the value into the HTML, you need <%= @title %> instead. Fix that, and everything should work correctly.

Treehouse TeacherHere's a snapshot of a Workspace with a working delete route: https://w.trhou.se/hcj51gqayh
Your route code looks identical to mine, so I don't think that's the problem. Are you sure that it's not deleting the file? Maybe it is deleting the file, and it's the redirect to / that's failing.
When you click a delete link, the Sinatra log in your terminal should look something like this:
70.185.39.169 - - [05/Jun/2018:21:41:02 +0000] "DELETE /Nick%20Pettit HTTP/1.1"
303 - 0.0262
10.120.36.5 - - [05/Jun/2018:21:41:02 UTC] "POST /Nick%20Pettit HTTP/1.1" 303 0
http://port-4567-qg8awkdmw1.treehouse-app.com/Nick%20Pettit -> /Nick%20Pettit
70.185.39.169 - - [05/Jun/2018:21:41:03 +0000] "GET / HTTP/1.1" 200 126 0.0200
10.120.36.5 - - [05/Jun/2018:21:41:03 UTC] "GET / HTTP/1.1" 200 126
http://port-4567-qg8awkdmw1.treehouse-app.com/Nick%20Pettit -> /
Especially important are those 200 status codes, which mean "success". If you're getting a different status code on one of those requests, that's where your problem is.
If you're still having trouble, please post your full wiki.rb code (or a Workspace snapshot link), as well as a Sinatra log snippet showing what happens when you click a delete link.

and this is what my terminal logs.
