After upgrading Wordpress to 2.9.2, I wasn’t able to login at the admin page of this blog.
By disabling all plugins I was able to login again. After that , I have enabled every single plugin, one by one, until a found out that qTranslate was the cause of this failure. (Google for “Disabling Wordpress plugins” if you don’t know how to do that).
A few hours after Googling for a fix, I couldn’t find any useful information. However, this error happened with me in the past and it as due to the desynchronization of the “AUTH_KEY” on wp-config.php file and the “wp_default_secret_key” in my language file (wp-content/languages/en_US.php).
I went to the en_US.php file and it was ok, the keys were equals. So I deleted this file, just to see what would happens. Voilá! It was working again.
So, the fix is as simple as:
rm /<installation folder>/wp-content/languages/en_US.php

Introduction
I have started thinking about producing some Kiteboarding T-Shirts and perhaps start a small Kite Wear Company about six months ago. As a software developer, I am comfortable with computers and I thought I could do the designs myself, after watching some Illustrators Tutorials on the internet. I quickly realized that I was completely wrong. I have no skills neither talent to create artistic designs. Thus, I went to the Auto Tracing Tools, such as Corel Trace and some others.
Their result were even worse than my manually generated designs.
I had no choice, if I wanted to produce high quality t-shirts, I would have to hire a professional designer.
I did some budged estimates and I almost gave up due to the high cost to produce a vector design. It was about U$100,00. To be honest it is not that expensive for an established company. However, I don’t have a company, I was not even thinking about opening one. I was willing to produce small quantities of 5 or 10 different designs. In this case, the U$100,00 for images would be too expensive.
In order to produce T-shirts with good quality and an affordable price, we have to find and talented and affordable designer and a base image to start.
Requirements
This paragraph is to explain what are the requirements involved in the life-cycle of the t-shirt production, such as tools, prototyping, vectorization, printing, colors, fabric types and cuts.

I am now the proud owner of the Dattein.com domain.
For the trifle of U$50,00 I got the perfect domain for my personal blog.
Ok, I know, you should be saying: “Who cares?”
