I got the error and am not using WP Rocket on the site.

Fatal error: Declaration of Automattic\WooCommerce\Internal\DependencyManagement\ExtendedContainer::get($id, bool $new = false) must be compatible with League\Container\Container::get($alias, array $args = Array) in /wp-content/plugins/woocommerce/src/Internal/DependencyManagement/ExtendedContainer.php on line 18

P.S. For anyone who’s website is broken, look for an email sent to your admin email address for recovery mode to deactivate the plugin until the issue is fixed.

Hi Carolina!
I had this problem when installing other plugins also!
There are several ways to fix this, you can pick one of the methods below:
Method 1: FTP Access
You can log in to an FTP program such as FileZilla, I reccomend this.
Simply get your FTP information by logging into your host (provider), and selecting “FTP Details” or “View FTP” or “FTP Access”, or etc.
When you get your info, log in to FileZilla, go to public_html, then to wp-content, then go to plugins, and select Jetpack. Right-click it, and tap “Delete”.
Now you can simply download this plugin again and you will not get this error.

Method 2: Use File Managers’ (RECOMMENDED)
Get your FTP details like last method. Fill it into one of the links below:
1. 000webhost Official File Manager
2. Windows-Looking 000webhost File Manager
simply select “FTP Editor”, or “File Viewer”, or “Manage Files”, or etc. From here again, go to public_html, then to wp-content, then go to plugins, and select Jetpack. Then delete it…
Now, reinstall Jetpack…
Method 3: Use Built-In FTP
When you log in to your host, and select your website, then you can simply select “FTP Editor”, or “File Viewer”, or “Manage Files”, or etc. From here again, go to public_html, then to wp-content, then go to plugins, and select Jetpack. Right-click it, and tap “Delete”.
Well again, you can reinstall your plugin agian.
