Can't upload my solution to a weekly challenge?


Worked for me!




Hi. I am trying to upload solution for Challenge 121 (challenge_121_*.yxmd), this is my first time.  All the time I have an error :  "The contents of the attachment doesn't match its file type"

Hi @marisha



Sorry to hear that and thanks for reporting this issue. It is usually related to OS/security/browser settings. I just sent you an email. Please check your inbox. Thanks

Hi there,


Whenever I try to upload a solution to a weekly challenge it says it has been posted successfully but the post never appears!


Can you take a look at this please?


Kind Regards

Hi @dsmdavid

Thanks for reporting this issue. We are still investigating it. There is a workaround though. Please zip your files and upload them. I hope it will help.

Thanks, @JacquesC Still get the same error even with zip files. Hosting the files elsewhere and adding the link as a workaround.
