  <p>I think the problem comes with the PNG picture that is being rendered by default on the contact page. All of the code is the basic code that is given by the Yii framework: <a href="https://github.com/yiisoft/yii2/releases/download/2.0.5/yii-basic-app-2.0.5.tgz" rel="noreferrer">here</a> Only happens when I click the <code>Contact</code> tab on the navigation bar.</p>
