After quite a few searches, for what it turned out were the wrong questions, I found the solution. Wanted to share it out there for others as this issue has a way of hiding itself due to the nature of how it came about.
Scenario played out this way…client called and had lost their ability to use the TinyMCE Visual Editor in Blog Posts, as well as, the text editor was displaying white text…..so even that was unusable.
We use Divi by Elegant Themes a lot, and the Divi Page Builder was also affected by this issue.
One of the best parts about using a clean slate like the Divi WordPress theme, is the enormous amount of options you are given to create what you want, your way. The bonus is, thousands of creative minds out there do the same thing every day, and that knowledge base is available online with a little searching.
