I added woocommerce to my new wordpress website & all is gone HELP

Hi, Alen. Thanks for using Lightsail.

Normally, you can access your wordpress dashboard by visiting the /admin page relative to the root of your wordpress site. So, if your site were at www.example.com, you would go to https://www.example.com/admin. That URL should still be accessible even if the main website fails to render.

If the entire site is down because of an error in your plugins you can disable all plugins using the following procedure:

1. login to your instance via SSH (web-based or using your own SSH client).
2. Once logged in you can disable all plugins by moving the plugins directory to a backup: mv ~/stack/wordpress/wp-content/plugins ~/stack/wordpress/wp-content/plugins.backup
3. Reboot your server to make sure all wordpress processes are running again.

This will most likely disable plugins that you want/need. My suggestion would be to copy each of the plugins back into the ~/stack/wordpress/wp-content/plugins directory and test to see if they break your site.

I hope this helps!
