 * I am trying to setup the Fluent Support plugin. I am stuck on Step 1. When I 
   click “Next Step”, I get the following error: “No route was found matching the
   URL and request method”. Looking at the headers, I see that the setup file is
   failing with a 404 on a GET request. However, when I look at the json and the
   plugin code, I only see a POST request mentioned for this URL: /wp-json/fluent-
   support/v2/settings/setup/
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcannot-setup-plugin-3%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * As a follow-up, we are on a multisite. I tested the plugin as both network activated
   and site-activated, and it fails on both. I have cleared permalinks and I am 
   on WordPress 7.

 * Hello [@jakifrisina](https://wordpress.org/support/users/jakifrisina/) ,
 * Thank you for the detailed report.
 * I have tested the issue on our end and working fine. It seems like a site specific
   issue.
 * We also checked the Fluent Support setup route, and the setup endpoint is registered
   as a **POST** route only:
 * `/wp-json/fluent-support/v2/settings/setup/`
 * The admin setup screen should also call this endpoint using **POST**, not GET.
   So if your browser Network tab shows this URL being requested as **GET**, that
   usually means something on the site/server is interfering with the REST request,
   or the admin JavaScript being served is stale/corrupted.
 * Please check the following:
    1. Clear all site/server/CDN cache, then hard refresh the Fluent Support setup 
       page.
    2. Temporarily disable any security, firewall, REST API restriction, or optimization/
       cache plugin.
    3. If you use Cloudflare or a server WAF, check whether POST requests to `/wp-json/`
       are being blocked or rewritten.
    4. Re-save WordPress permalinks once more.
    5. On multisite, please test Fluent Support as **site-activated** on the specific
       subsite first, then run the setup from that same subsite dashboard.
    6. Make sure the plugin files are fully updated/reinstalled, in case the admin 
       JS file is from an older/cached build.
 * The error message itself means WordPress received a request method that does 
   not match the registered REST route. Since the plugin registers setup as POST,
   a GET request to that endpoint would return this type of error.
 * Thank you
