Hello @115354477660514 ...
Are you asking about Canvas or Canva? These are two completely different products. Canvas is the LMS (Learning Management System) that many schools use to host their online courses. The Canvas Community website (which you are using now) is for users from around the world to come and ask questions about the Canvas LMS and to check out written/video tutorials about Canvas...among other things. Canva, on the other hand, is a website where people can design things like banners, images, and other visual content.
If you are asking about Canvas and are seeing an error message like the one you've described, I would suggest that you reach out to Canvas Support: How do I contact Canvas Support? - Instructure Community.
If you are asking about Canva, here is the support portal I found on their website: Canva Help Center.
Keep us posted if we can be of assistance with Canvas...thanks!
