All upload buttons are inactive (OJS3)

While in journal setup wizard, image upload buttons don’t respond to click. Need help. Thanks.

The logo upload button did respond but produce an error message:

“The system file uploader is loading. If it doesn’t appear it is likely that none of its runtimes is supported by
this browser. Please, contact administration for support.”

Hi @Paul_Chen,

You’re probably running into this error:
