So if you have been seeing this line in your Safari console:

[Error] Failed to load resource: The file “purify.js.map” couldn’t be opened because there is no such file. (purify.js.map, line 0)

And wondered what in the world is going on, you're in luck because I'm here to tell you. Apparently if you are a grammarly user and have the Safari extension installed and enabled, you will see this error. Hopefully it will be addressed soon, but in the meantime it isn't anything to be worried about.

You're welcome.
