How to connect instance using browser-based SSH client?

To connect to your instance using a browser-based SSH client, you can follow these steps:

1. Sign in to the Amazon Lightsail console.

2. On the Lightsail home page, go to the "Instances" tab.

3. Find the instance you want to connect to and choose one of these options:

   • Click on the quick connect icon
   • Click on the actions menu icon (⋮) and select "Connect"
   • Click on the name of the instance, then on the "Connect" tab, choose "Connect using SSH"

This will open a browser-based SSH client, providing you with a terminal screen where you can interact with your instance. You can then use Linux or Unix commands to navigate to your WordPress installation directory and delete the problematic plugin.

The browser-based SSH client is the quickest way to connect to your Linux or Unix instances for administrative tasks like this. It doesn't require you to install an SSH client on your computer, configure key pairs, or specify administrator passwords. This method works even if you've lost or deleted the original SSH keys you configured when creating the instance.

Once connected, you can use command-line instructions to locate and remove the plugin that's causing issues with your WordPress dashboard. Remember to be cautious when deleting files to avoid accidentally removing critical components of your WordPress installation.
