Does Flywheel support Multisite?


Flywheel supports multisite on our Personal plans and above (not the Tiny plan). As with all plans on Flywheel, we calculate plans based on traffic, bandwidth, and disk space limits. Multisite is no different, except that all subsites within your multisite installation cannot exceed your limits when added together.


For more information on plan limits and how they’re calculated, see the help article: What does Flywheel count as a “visit”?

To enable Multisite, visit your add-ons tab and select the multisite add-on. We support both types of multisite installations:

Type Description Example
Sub-directories A path-based network in which on-demand sites use paths
Sub-domains A domain-based network in which on-demand sites use subdomains

Additionally we support the installation of “domain mapping” to run multiple unique domains with a single installation:

Type Description Example
Domain Mapping A domain-based network in which on-demand sites use unique full domain names

Historically, domain mapping required a plugin. However, as of WordPress version 4.5., it’s also possible to implement multisite domain mapping natively, as part of WordPress. To get your multisite set up properly to take advantage of this capability, just reach out to our support team.

Alternatively, you can use a plugin like WordPress MU Domain Mapping. Doing so requires you to add define( ‘SUNRISE’, ‘on’ ) in your wp-config.php. You can choose to enable sunrise automatically when you enable multisite from the Add-ons tab of the Flywheel dashboard. (If you need Sunrise enabled after the fact, just contact Flywheel support and we’ll be happy to help.)


For more information on making changes to your wp-config.php file, see this article: How do I make changes to my wp-config.php file?

It’s important to note that getting multisite up and running is a bit tricky, especially in cases where there’s domain mapping. All of the various configuration options must be set correctly, or you’re likely to run into issues related to cookies, redirect loops, or even database connection problems. If you experience any issues with your multisite install on Flywheel, contact the WordPress experts at Flywheel support and we’d be happy to help get you up and running.
