3-legged oAuth error on Authorize.aspx

[Aleksandr Borisov]

Hello! I try Authorize on 3-legged method,
I follow the generated link (example - https://authentication.fatsecret.com/oauth/Authorize.aspx?oauth_token=1ddc98b4b3a7479583d16e954837347d), then enter the login password, but nothing happens, I only get an error in the console. Please tell me why this is so? As a result, I can't get the code.

Screenshot added.

Help me please, thx.
