It's now time to run your Joomla site on at least PHP 7.1. as PHP 7.0 has reached its end of life and is no longer being developed or supported, except for security updates for a few more months. How to change the PHP version your Joomla site is running on is what today's Maintenance Monday is all about.

If you are getting the following warning on your Joomla Admin console, this tutorial will help you: "Warning Your PHP version, 7.0.31, is only receiving security fixes at this time from the PHP project. This means your PHP version will soon no longer be supported. We recommend planning to upgrade to a newer PHP version before it reaches end of support on 2018-09-03.

Joomla will be faster and more secure if you upgrade to a newer PHP version (PHP 7.x is recommended). Please contact your host for upgrade instructions."

The Template Module Position Preview Mode is a great tool when you are debugging and developing your Joomla site. It's also very useful for seeing what module positions are available in a web site you take over from someone else. However, leaving this setting enabled gives away info that hackers can try to use against you. How to disable the Template Module Position Preview Mode is what today's Maintenance Monday is all about.

The caching system in Joomla allows for faster page load speeds. Instead of recreating every last little bit of each page each time it is called for, the caching system takes snapshots (if you will) of sections or even whole pages.

This cuts down on the time it takes to draw each page on your site as visitors request them within the period of time you set your cache items to expire. How to enable caching in the Joomla configuration is what today's Maintenance Monday is all about.

If you have your Joomla site using an SSL Certificate but someone links to the HTTP version of your site (or they enter in the HTTP url of your site to visit it), modern browsers will display a "Not secure" flag to your visitors unless you force that traffic through the HTTPS version of your site. How to force site access through only HTTPS is what today's Maintenance Monday is all about.
