Right, the Fluida help forum has come up with an answer that has worked for me, hopefully it will work for you too! 🙂
In the Theme’s settings (specifically in the ‘Comments’ part of the ‘Post Information’ option of ‘Customize’), there is an option under “Comment Field Label”. Change this option to ‘Label. This simple change seems to have fixed the identical problem for me, so maybe it’ll work for you 🙂
I’ve noticed the same thing has happened to my site too – currently running Fluida 0.9.9.1. I’ve not made any changes or installed any new plugins in the last few days, so I’m going to assume a recent Fluida update is now clashing with this plugin.
