Could you please provide the example URL? 

I'm looking at making our forum a bit more intuitive for users as we've had a few posts with no content. I can see that there is a text box with a placeholder by default, which I edited under Phrases. On page load, this box is replaced, I was wondering how to disable this behaviour? I've deactivated all optimisation plugins and found that it's not caused by any of them. I've also changed the Posting & Editor settings.
