Well, I found the problem. As I stated in my first post regarding this issue, I was using a child theme. When I looked at style.css, it read, in part:
*/
/*
Add specific style overrides here…
Just for example, this style will change the default BG Color for the site. */
body,
input,
textarea {
background-color: #CCC;
}
Might I respectfully suggest that in updated versions, the style be included in the comment so it doesn’t *actually* change the default bg color for the site, or at least the text area? That really required a fair amount of troubleshooting time, you know?
Anyway, thanks for your attempts to help, & I hope my suggestion is taken in the spirit in which it was given.
