Frequently asked questions.
Can I use Ultimate Multisite on a regular WordPress site?
No. Ultimate Multisite requires WordPress Multisite and is designed specifically for network installations.
Does Ultimate Multisite support custom domains?
Yes. Ultimate Multisite includes robust domain mapping with automated DNS verification and guided setup for end users.
Which payment gateways are supported?
Stripe, PayPal, and manual payments are supported out of the box.
Does Ultimate Multisite support passwordless login?
Yes. Ultimate Multisite includes native passwordless login with passkeys when the browser supports WebAuthn and short-lived email one-time codes as a fallback.
Can I migrate from WP Ultimo?
Yes. Ultimate Multisite is a community-maintained fork of WP Ultimo 2.x. Migration happens automatically when the plugin is activated.
Will Ultimate Multisite work with Multisite with Subdirectories?
Yes. Ultimate Multisite supports both subdirectory installs and subdirectory installs.
Will Ultimate Multisite work with Multisite with Subdomains?
Yes. Ultimate Multisite supports both subdirectory installs and subdomain installs.
Can I use Ultimate Multisite to limit which Plugins and Themes users can use?
Yes. With Ultimate Multisite you can select which plugins and themes are available to each plan on your network.
Can I use Ultimate Multisite to limit the number of posts a user can create on their site?
Yes. With Ultimate Multisite you can establish post quotas for every available post type on your network. You can also limit the number of users the admin can invite, the amount of disk space, and much more.
Does Ultimate Multisite support Site Templates?
Yes. With Ultimate Multisite you can create as many Site Templates as you want. Site Templates are not themes, they are normal sites on your network. You can activate plugins, themes, and customize that Site Template in any way you want. If a user selects that template, his or her site will be created as a copy of that template, with all the customizations in place. You can also set a particular template for a plan. By doing that, every user that signs up on that plan will have his or her site created as a duplicate of that Site Template.
Does Ultimate Multisite integrate with WooCommerce?
Yes! If you want your network users to have WooCommerce available for them, allowing them to set up stores, that is possible using Ultimate Multisite. You can even limit the number of products your clients will be able to create on each plan tier. In terms of subscription payments for Ultimate Multisite, you can use the Ultimate Multisite: WooCommerce Integration Add-on to allow your Ultimate Multisite clients to pay using WooCommerce gateways on your main site. In that way, you can tap into the huge library of payment gateways developed for WooCommerce and use them to bill your Ultimate Multisite clients.
Is there a way to migrate subscriptions from WPMUDEV Pro Sites?
Yes, Ultimate Multisite now offers you a helpful tool to get you to migrate your Pro Sites network.
Why is the “Allowed Plugins” tab empty on my Plan Edit Page?
Ultimate Multisite only lets you allow or deny access to plugins not network-activated on your network. When a plugin is network-activated, by its very nature, it will be loaded by default on every site of your network. If you do not see any plugins listed on the “Allowed Plugins” tab, check if the desired plugin is network-active or not.
Can I use my own Pricing Table design?
Yes. Since version 1.4.0, Ultimate Multisite supports template overrides.
Does Ultimate Multisite work with WP Engine?
Yes. Ultimate Multisite was always supported by WP Engine, but getting domain mapping to work required manual extra steps from the admin (adding the domain to the WP Engine panel). This is no longer the case since version 1.6.0. Ultimate Multisite integrates directly with the WP Engine API and domains get added to the panel automatically after mapping.
Which hosting provider do you recommend?
Ultimate Multisite should work with any hosting provider. The only difference is that some hosting company like Closte, Serverpilot, WPMUDEV, WP Engine, Cloudways, Gridpane and Runcloud.io has a tighter integration for domain mapping capabilities so they work out of the box. For other hosts that don’t use cpanel, you may need to set up domain mapping manually. For a private server with a dedicated IP, the webserver can be setup to serve the wordpress install by default and no extra steps are required for domain mapping.
Site screenshots show a Cloudflare challenge page instead of the actual site
Ultimate Multisite uses Microlink as its primary screenshot provider and falls back to thum.io if Microlink is unavailable. If your network is behind Cloudflare with Bot Fight Mode or similar protections enabled, the screenshot service may be blocked and return a Cloudflare challenge page instead of your site screenshot.
Solution: Create a Cloudflare WAF exception rule to allow the screenshot service crawlers, or temporarily disable Bot Fight Mode for screenshot generation.
Note: Screenshots require sites to be publicly accessible. Local development environments cannot generate screenshots regardless of Cloudflare settings. Microlink’s free tier allows 50 screenshot requests per day without an API key — this is generally sufficient since screenshots are only taken once per site at creation time.
