Planned Community Maintenance - 11th August, 7am-10am

1 minute read time.

Hi everyone,

We’re writing this afternoon with an important update.

Tomorrow morning, Tuesday 11th August, the Community will be entering a read only state from 7am until 10am.

This is to allow us to fix two issues that we know users are experiencing just now. This maintenance will fix the below:

  • Logging in issue where users are receiving the error message ‘the user already exists’. See below a screenshot of the error message:

    Image showing the error reading: The current user is already registered in Online Community platform.

  • Being logged out every 30 minutes or so.

Whilst in a read only state, you will still be able to view the Community and read all of the discussions on the site, but you will not be able to log in or post. The main Macmillan website ( will also be unavailable from 7am-10am.

If you feel you need some support in the meantime, please remember our Support Line is here for you. Our teams are available 8am-8pm, 7 days a week on freephone 0808 808 00 00, or by email or webchat

We’d like to say a huge thank you for your continued support and patience with us whilst we carry out these fixes.

If you have any feedback about the new site, or there’s anything the team can do to support you then please don’t hesitate to get in touch with us on

Best wishes,

Ellen, Rachel, Tom, Steph and Eliza
The Community Team
