I'm getting this message on my dashboard: Unfortunately, one or more of your preferences are now unavailable. Please update your preferences, or remove gadget by clicking delete from the title bar above.

How to fix it, please?

Hi @Natalia Melnichanskaya -- Welcome to the Atlassian Community!

It may help if you post an image of the dashboard showing the error.  That may provide some context for the community to offer suggestions.

Which gadget on your dashboard is showing this error message?

And is it one of the built-in gadgets or one added by a marketplace app?  If it is from a marketplace vendor you may need to contact their support team for assistance.

Kind regards,
Bill
