This issue should be resolved in the 2.4 version. I left the Yoast check for now, but this warning will be removed in future versions.
If you have this warning, and the mixed content fixer does not work, please let me know.
When you have the force rewrite title function from Yoast active, the mixed content fixer of Really Simple SSL won’t work.
For both solutions, you’ll have to turn disable the force rewrite titles option in Yoast. You can find this option in SEO / Titles & Meta’s / General.
Step 2 option 1: Turn off mixed content fixer
Fix all your mixed content manually, and turn off the mixed content fixer in the settings.
Step 2 option 2: Get your theme to write titles itself
If you need the mixed content fixer, and the your titles disappear if you turn the Yoast option of, you’ll could add the title to your wordpress header.
- Look for the <head></head> tags. Most of the times you can find these in the header.php of your theme. Of course, if is best if you edit this in a child theme.
- Between these tags, add wp_title(), like so:
<title><?php wp_title(”); ?></title>
