FIX WordPress Blank White Page After Update To 4.3

Hi,

maybe someone noticed it – my site was offline yesterday after an update of WordPress to version 4.3.

I found an easy way to trace back the issue and fix it (this is why you can read this text now) and I want to share it here.

The problem

The problem I had was the so called “white screen of death”. People who would visit this site would see nothing. Just a white empty page.
This problem occurred after I started the WordPress update routine without doing a health check afterwards.
Another big issue was, that I weren’t able to login back into the dashboard. It feels as if WordPress just died and all your content is lost – but don’t panic. Here is a solution.

Make a fancy animated HTML5 Logo for your WordPress with pure JS (1/3)

I was very inspired by the amazing Google Doodles and decided to create my own animated HTML5 logo. There is an older post on how Google creates its Doodles on HTML5 Rocks: http://www.html5rocks.com/en/tutorials/doodles/lem/
In this post, Marcin Wichary explains some really helpful and advanced animation concepts and if you are interested in this stuff you should definitely read it. Unfortunately, I discovered this post just, when I had finished my own series. You will see that even the complexity of my “stupid” stickman logo is incredible. The Stanislaw Lem Doodle e.g. has 17,000(!) lines of JavaScript code and its own engine! Anyways..

This will be a beginners series about animating the WordPress header/logo. I will try to keep it simple but informative.
One thing in advance: please use the described techniques carefully and ensure that visitors are not annoyed (I’m not a good example – I don’t care about my visitors 😉 )

We will not use jQuery or any other framework. Everything will be written in pure JavaScript. The only HTML we will produce is a HTML5 canvas tag. It should be no problem, if you’re not familiar with canvas and HTML5 technologies. However, if you do not know much about it, I promise that there is a lot you can learn in this series. The template for this series is the current standard WordPress theme which is “Twenty Thirteen” and my own (super creative) stickman logo.
