I was working on chapter 9 from the Agile Web Development with Rails. I noticed that clicking on the “Add to Cart” button did not work. I checked my code a few times and found that the code was fine.

I could not find anything useful using the Google search.

I remembered a quote from one of the Sherlock Holmes adventures, “When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.”

I started going through the potential issues that I could think of:
1. I thought I incorrectly typed the code. I even tried to copy and to paste the code from the book. Problem was still there…
2. I checked the logs and thought that the database was not working. I saw the database query worked correctly. I even restarted the MySQL server.
3. I tried using Safari to access the project (I usually use Firefox). I wanted to make sure that I could reproduce the problem with a different browser. The problem was there. “Interesting” was the word that came to mind.
4. I restarted Mongrel and the problem persisted. Hmmm… OK.
5. I restarted my Mac. Silly me…
6. Finally, I thought that I might have used an older version of Rails since I created the depot project and Rails defaulted the version to 1.1.6.

I have been using Ecto to post my blog entries.

Unfortunately, upgrading to Wordpress 2.1 causes Ecto to stop downloading the entries to my computer.

As always, Google is your best friend.
I did a search on “wordpress 2.1 ecto” and got many entries.

The first entry shows how I can fix the problem (thank you, Erik!).

The issue can be fixed by downloading the xmlrpc.php file from http://trac.wordpress.org/attachment/ticket/3662/3662-xmlrpc-categoryId.diff (thank you, Lloyd!).

During my Java class, we have 2 different deployment machines: one for the MySQL server and another for the web server.

Since the remote server is not configured to accept any ftp connections, I am forced to use scp. It’s a pain to manually scp my file manually to the web server, so I did a bit of research and found a good way to securely copy my file (to the web server).
