Adding a comment now says "Add your custom text here"

I changed web hosts and though for the most part is was awesome, one glitch is that I’ve noticed at the bottom of my blog posts where I welcome comments it now says “Add your custom text here”. How can I change that to say something like “Please add your comment here” or something else. I’ve looked around but haven’t seen a fix for this particular problem.
Thank you (again) as always!

an example post would be here: The Love of a Father

Hello there,

I hope you are doing well today.

Are you using a comments plugin on the website?

Best Regards,
