Step 1. Appearance > Theme Editor
Step 2. Find header.php at right side {Theme Files}

Add a meta in html head
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

If you don’t want REDO the complete procedure, a good fix would be to use
STOP SLAVE;
SET GLOBAL sql_slave_skip_counter=1;
START SLAVE;
If there are too many such errors, a good idea would be to automate it using a bash script.
