I recently started using Local by Flywheel for a WordPress multisite network and encountered a consistent redirection issue.

Whenever I access the wp-admin dashboard of a newly created subsite (e.g., sub-site.site.local/wp-admin) or even the main site, I am immediately redirected to the main site’s wp-signup page (site.local/wp-signup). Interestingly, appending a trailing slash to the URL (e.g., site.local/wp-admin/) resolves the issue, the issue only happens when I’m not logged in.

Thanks In Advance

Steps can be taken to replicate the issue

Create a New WordPress Multisite Project:

• Set up a new WordPress project in Local, enabling the multisite feature with subdomains.
  Access the Admin Dashboard:
• Open a private browsing window.
• Navigate to the URL yourdomain.local/wp-admin without including a trailing slash at the end.

System Details

Local Version:
Version 9.0.2+6676

Operating System (OS) and OS version:
Windows 11

Steps I’ve tried to resolve the issue include:

• Creating a new project without any plugins, which resulted in the same redirection behavior.
• Implementing a mu-plugin to override the redirection without success.
• Switching the server from Nginx to Apache and modifying rewrite rules in the .htaccess file, but the problem persisted.
• Could you please assist me in resolving this redirection issue? Thank you for your help!
