 * Im currently in Litespeed Cache > Cache > Object.
 * I have installed LSMCD on my VPS according to your guidelines here: [https://docs.litespeedtech.com/products/lsmcd/getting_started/](https://docs.litespeedtech.com/products/lsmcd/getting_started/)
 * The connection test on my VPS using “telnet 127.0.0.1 11211” worked.
 * Still for some reason, the plugins shows “Connection Test: Not Available”
 * See screenshot: [https://i.imgur.com/U9Sw0P8.png](https://i.imgur.com/U9Sw0P8.png)
 * I cant find anything about this issue in your documentations.

 * Hi,
 * Because you need to install the memcached extension for PHP as well
 * not sure what is your server OS and environment
 * if it is LiteSpeed native server ,then :
 * if it uses yum , then do `yum lsphp??-memcached` , if it uses apt , then do `
   apt install lsphp*-memcached`
 * if it uses other control panel , then follow it as your panel’s way to install
   PHP extension
 * after that run `pkill lsphp` , refresh your page
 * then you should see it shows up
 * Best regards,

 * I am running LiteSpeed Web Server Version: 5.4.11 (build 6) on Centos 7.
 * Are you sure the commands are correct? After running `yum lsphp??-memcached`,
   i receive
 *     ```
       Loaded plugins: fastestmirror, universal-hooks                                                               
       No such command: lsphp??-memcached. Please use /bin/yum --help  
       ```
