WordPress Cache and How It Can Improve Your Website Speed

15 MIN READ

Nearly half of the World Wide Web is powered by WordPress, but somehow there’s a common misconception that WordPress websites are slow and laggy. In this article, we’ll give you full information about one of the techniques that can highly improve your website performance, WordPress caching. Caching is a technique that allows you to store the result of a long-running task in a fast access memory, and then reuse that result without actually doing the task. This means that cached content is displayed a lot faster than content that’s loaded directly from the server. It’s like memorizing your multiplication tables. Once you have memorized it, it’s so much faster to recite the answer to a multiplication problem off-hand than trying to calculate the answer all over again. Caching can be performed in different stages of a running web application, so every stage is called a cache layer. We’ll go through…

In this article, we’ll find ways to troubleshoot timeout errors and find solutions for them, while giving you a better understanding of timeout errors and their causes. What is a 504 Timeout error? To deeply understand what a 504 Gateway Timeout error is let’s first have a look at server and client relationships. What happens when the client sends an HTTP request to the server? When the server receives the request, it processes it, and–depending on whether the result is successful or unsuccessful–returns a response with the corresponding HTTP status code in the HTTP response headers. HTTP status codes are a…

9 MIN READ

Are you wrecking your brain trying to figure out the stacking order of HTML elements? Let us lend you a helping hand and do the heavy lifting for you. First things first, here’s what you need to know about the z-index: The z-index CSS property sets the z-order. That’s why developers use it to determine the order in which elements are positioned within the stacking order. Usually, 2 types of errors occur. The first one is because the z-index only works when an element is a) a positioned element, b) a flex item or c) a grid item. Positioned element refers to an element whose position property is other than <static>. Flex items are elements whose parent element’s display property is <flex> or <inline-flex>.
