 * Composer detected issues in your platform: Your Composer dependencies require
   a PHP version “>= 8.0.0”.
 * There has been a critical error on this website.
 * Hi, I was able to roll back the plugin to fix this error before via ftp, but 
   now I cannot find the plugin via ftp. The content plugins folder no longer shows
   all of the plugins. not sure what to do.
 * I am considered reinstalling everything on a new server with newer php version.
   thanks
 * James

 * Based on the context, it sounds as if you are updating a plugin and the environment
   is just not supporting it. If plugins are managed via composer, and you are getting
   this error, they may be missing due to an incomplete run of your composer install.
 * You should really check and update your PHP version though if this is failing.
   even PHP 8.0 is end of life and 8.1/8.2 are on their way out. I’d recommend getting
   it up to PHP 8.3 so you actually are running a supported version which should
   also in turn fix his error and get your plugin installed

 * Hi, thanks for the response. I use WordOps and the latest version of Unbuntu,
   but I cannot get newer versions of php to install. tried multiple ways
 * Not sure If I should destroy my server and start a new one from scratch.

 * The message can be caused by plugins or themes that use Composer to provide an
   autoloader for their own functions. It is rather not completely thought through
   by the developer if such a message appears because you can easily prevent it 
   with an option.
 * You say the plugin that was to blame before is no longer there? Have you also
   looked in mu-plugins (the must use plugins are there)? And then be sure to check
   the themes, especially the active theme (the others are not executed).
 * Your aim should first be to find the cause of the current message. It is not 
   necessary to change hosting or set up a new server. If you have found the cause,
   I would also recommend that you report the problem to their support so that they
   can solve it better in a future update.

 * I use WordOps on Ubuntu 24.04 LTS, and I have multiple sites running PHP 8.3 
   and 8.4 on the same tiny $5/m server.
 * Upgrading PHP on WordOps to, say, PHP 8.3 should be as simple as running the 
   [command](https://docs.wordops.net/commands/site/#usage_1):
 * `wo site update example.com --php83`.
 * Even if you don’t have PHP 8.3 “stack” installed already, this simple command
   will download and install PHP 8.3, and configure it for the specified site. (
   Of course, ensure you have up-to-date backup before you run any shell commands.)
 * If the above command doesn’t work for you, then your WordOps instance is broken
   somehow… and their community support forum would be the best place to seek help:
   [https://community.wordops.net/](https://community.wordops.net/)
 * Good luck!

 * Thanks for the reply. I tried for a longtime to fix it but got a new server.
