Step 3: Go to the ‘SSL Insecure Content’ option under the settings tab.
Step 4: This is the final step where we set up the new plugin to fix mixed content. There is 5 level of fixing available. In my experience, ‘content’ level has always fixed all of my mixed content issues. However, you can move up the levels in case you realize no changes with ‘content’ level.
I recommend leaving all the other changes intact. Click the save changes button at the bottom. Saving the changes will automatically log you out of the WordPress back end.
If you followed all the steps, your website should have a green padlock. We have successfully fixed the mixed content error in WordPress.
NOTE: The plugin needs to remain activated to handle mixed content on your WordPress website.
