Bug Description

When activating the SQLite module, users receive a warning:

Warning: Do not activate if your site is implemented in a multi-server environment

This message is somewhat confusing, when I read it originally I thought it referred to WordPress multi-site. @felixarntz clarifies that: "Since SQLite puts a file into the filesystem, it won't work on a site that is across multiple servers (some enterprise sites etc.)"

That sentence explains the reasoning much more clearly, maybe we can use that instead? Alternately, remove the confusing language entirely since it only applies to a very small percentage of sites.

Steps to reproduce

1. Install the plugin
2. Check the settings screen
