Why is Infinite Uploads showing “upload folder is not writable” after migrating my WordPress site?

This issue typically occurs due to server configuration settings. In your case, it was caused by the allow_url_fopen setting being disabled on the production server.

To resolve this, enable allow_url_fopen in your server’s PHP configuration. This setting allows PHP to access files via URLs, which Infinite Uploads relies on to verify writable directories and connect to cloud storage.

If you’re unsure how to enable this setting, contact your hosting provider or system administrator, or use WP-CLI to check for configuration issues:

wp infinite-uploads verify  

This command tests the connection and can help identify server-side restrictions or misconfigurations. Once allow_url_fopen is enabled, the “upload folder is not writable” error should be resolved.
