In case the issue persists after the update, please also check for custom nginx configuration templates, as the fix is only applied to the default templates.

If affected, you may add a ^~ to the custom template at

/usr/local/psa/admin/conf/templates/default/domain/nginxDomainVirtualHost.php

specifically at the internal-nginx-static-location directive like so:


       
       
    location ^~ /internal-nginx-static-location/ {


Workaround

If update is not possible for some reason you may try the following


workaround

1. Log into Plesk.

2. Go to Domains > example.com > Hosting & DNS tab > Apache & nginx Settings.

3. Disable Smart static files processing or enable Serve static files directly by nginx.

Note: when enabling Serve static files directly by nginx, mod_rewrite rules will not be applied
