Error: memcache missing memcached

What's Causing This Error

The error "memcache missing memcached" occurs when the PHP Memcached extension is not installed or enabled on the server. Memcached is a distributed memory caching system that is frequently used to speed up database-driven websites by caching data and objects in memory. Without installing and enabling the Memcached extension, PHP applications cannot connect to a Memcached server to store or retrieve data.

Solution - Here's How To Resolve It

To resolve this error, you can install and enable the Memcached extension on your server. The installation process varies depending on your operating system and web server.

For example, on Ubuntu or Debian systems, you can run the following command to install the Memcached extension:

sudo apt-get install php-memcached

On CentOS or RedHat systems, you can use yum instead:

sudo yum install php-memcached

After installing, you should add the extension to your PHP configuration file (php.ini). You can do this by adding the following line to your php.ini file:

extension=memcached.so

Once you have installed and enabled the Memcached extension, restart your web server and the error "memcache missing memcached" should be resolved.
