About Mailenable Webmail 8.0 License

[fuegoletal]

Hello,
I am a plesk panel user and i have my webmail on a "Mailenable Webmail 8" platform.
When i try to attach a file in a new mail this message appears: "The license for this software prevents access to webmail attachments".
Is that right? Do i have to pay a license for attaching a file?.

Thank you very much
