PHP performance is an enduring issue for web hosts. PHP is the most widely used server programming language on the web by a big margin. The most popular content management systems and ecommerce applications are written in PHP, including WordPress®, Joomla, Drupal, Magento®, and dozens more.  The ultra-fast PHP-FPM accelerates PHP execution on busy web servers, making it a valuable tool in the fight against slow sites and resource-constrained servers.  This article takes a deep …

We have all experienced the effects of mental fatigue after a long work week, and feelings of burnout near the end of a large scale project. 2020 has only amplified these effects with daily Zoom meetings and a lack of separation of work and home life. Many of us are stuck at home juggling our time between working in a spare closet (a.k.a. the home office), running a home school from the dining room table, and then …

Disk IO errors  (input/output) issues are a common cause of poor performance on web hosting servers. Hard drives have speed limits, and if software tries to read or write too much data too quickly, applications and users are forced to wait. To put it another way, storage devices can be a bottleneck that stops the server from reaching its full performance potential.  Disk IO is not the only cause of slow servers, so in this …

How to Check for Disk Space in Linux Servers are your virtual home and, just like your real home, they can become cluttered with unwanted junk.  In the case of servers, it’s not trash but data you have to kick to the curb every once in a while.  Without a regular clear out, data accumulates until it fills the server’s storage devices. Servers need to be able to write data to their hard drives. When …

PHP error logs are one of the most useful tools for diagnosing web hosting issues. It’s often difficult to find the cause of unexpected behavior in WordPress® and other PHP applications. PHP error logs, including WordPress logs,  can help you to spot problems and identify the offending plugin, theme, or custom code.  In this article, we describe what PHP error logs are and why they’re useful, before explaining how to use cPanel & WHM to …

File permissions are one of your server’s most important security features. They give you fine-grained control over who can read, write, and execute files. Without them, it would be impossible to safely host multiple users’ websites and data. However, incorrect permissions often cause hard-to-diagnose issues. If a website doesn’t load properly or software crashes, there’s a good chance misconfigured permissions are the culprit. They can also be challenging to manage with chmod, the standard Linux …

“Help, I can’t log in to WordPress!” is one of the most common WordPress hosting support requests.  Being locked out of WordPress is worrying, to say the least, but there’s no need to panic because you’re in the right place.  There are several reasons you might end up locked out of WordPress, and they are straightforward to resolve with cPanel & WHM.  In this article, we look at four of the most common login problems …

One of the more ambiguous, but oft-seen, errors resulting in support tickets is related to high server loads. While high server load errors are virtually never caused by the cPanel software itself or the apps it installs, these errors can certainly carry a degree of frustration. Given that the range of causes are not specified within the error itself, a degree of investigation is required. Generally speaking, this investigation will need to be done by the server owner, their system …

It’s super easy to install and manage SSL certificates in cPanel & WHM. Certificate requests and installations happen automatically with  AutoSSL and an  integration such as the cPanel Let’s Encrypt™ plugin. SSL automation saves web hosting providers time and eliminates the deluge of support requests that traditionally accompany SSL certificate issues.  AutoSSL includes a default certificate provider, which we chose for its reliability, usability, and generous domain and rate limits. However, we also made it …
