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.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
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:<\/p>\n\n\n\n
wp infinite-uploads verify <\/code><\/pre>\n\n\n\n
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.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"
