My WordPress reset on me

I lost my entire website. All of my posts and plugins.

your posts should be in your database, unless someone accidently or knowingly deleted your database.

Do you have a good back up of your database?

Your plugins should be at /wp-content/plugins/

if you dont have a good backup of your site, ask if your hosting provider has a backup. if they do, ask them to restore your site to that backup.

Always backup everything (including your database) before doing any actions, just in case something really goes wrong. It’s a great safety net
