Hello,
That message is coming from the "Accept.js" file from Authorize.
The plugin includes the a file giving a specific URL :
https://js.authorize.net/v1/Accept.js
You can take a look at that JavaScript file which define a "cdnPath" and try to includes another JavaScript files into the webpage : "AcceptCore.js"
Since the "Accept.js" includes some kind of hashes ; that file should not be process by any cache/optimization plugin.
We can find a lot of "page speed / optimization / minify" plugins for Joomla which can download external files and merge them into a bigger cache JavaScript file.
And if it's the case, if the file is update on authorize.net servers, the hash check will fail and you can have such kind of message coming from "AcceptCore.js".
Regards,
