Vienna downloading file 'iframe' on every post from "Fluent C++"

[mclow]

I created an entry from the web site "Fluent C++" - https://www.fluentcpp.com
Feed is here: https://www.fluentcpp.com/feed/

But when I read an article in Vienna, a small window titled "Downloads" pops up, informing me that it has saved a file named 'iframe' in my downloads folder.
It does this ON EVERY SINGLE ARTICLE.

Here's the contents of one such file:

Code: Select all

{"errors":[{"code":null,"code_name":"InvalidPlatformWidgetArg","detail":"Invalid parameter for 'redirectURI': file:///.","id":"2d4aebcd-8a0d-497e-8745-9564409c1ee5","source":{"parameter":"redirectURI"},"status":"400","title":"Invalid value for parameter 'redirectURI'."}]}
