Where to find the wp-config.php in Database local adminer

@angel, I don’t use Jetpack, so don’t have direct experience with what you’re doing here.

That said, this link (Offline Mode) includes this text:

You can turn on Offline Mode by adding define( 'JETPACK_DEV_DEBUG', true ); to your wp-config.php file.

So by adding that line, you’re doubling down in turning on offline mode, as it’s already enabled by detecting the hostname in your URL. Perhaps you should be setting it to false instead.

There also appears to be a filter that you can use to achieve the same, as covered here: How to get rid of Jetpack development mode | WordPress.org

Hope that helps!
