@chrisauthor Thank you! I was easily able to fix this on all three of my websites. I’m wondering how it happened on all three, although I do have a lot of the same plug-ins installed on all three.
Joy, I checked Site Health. It says my version of PHP requires an update, and that it’s a critical issue. So, I will figure out how to update it and post whether it helps or not. Thank you for the suggestion. Even if it doesn’t fix my issue, it needs to be done anyway!
Suman, I have the current version of WordPress, but the problem may be that my theme is so old (2012). I’m afraid if I try a newer theme, it will mess up everything on my website, and I don’t have time to redesign it right now.
Thank you both for your help.
