This isn't your fault, it's 100% mine. Probably a development error.
It's more than likely the article you were looking for doesn't exist because the ID (I use a unique number to identify each article from the database) was missing from the url (link) you pressed to get here or the page doesn't exist-scumbags!
You can visit my archive page now that lists all my articles I've written.
If the problem persists contact me on twitter, @d_azzopardi and I will get back to you straight away or if you want to send me the problem in detail, which is quite nice of you, you can complete my form and I will get back to you.
