upload from local button not working

[Ari-R]

Hi All, I have created and exported a layer to json, but when i try to upload it to use it again nothing happens. I have tried with a local version of navigator as well as the public site and get the same issue. I have also tried downloading layers from mitre attack site and I have the same issue.

I read a previous post that said updating the version on the config.json file might work but it hasnt made a difference. I have tried on safari and chromium browsers. Can anyone assist as to why im not able to upload layers?
