I did another check. I uninstalled ALL my plugins. No problems.
Then I just activate Yoast SEO Version 3.2.3 and I get the same problem.
1. Visual editor is gone unless I click on Text first and then Visual
2. The new textbox for URL links is way down in lower left corner of page.
3. Textbox settings popup does not work.
I can’t notify Yoast because they only take support issues from licensed buyers.
