Hello,
I also face this issue. I was able to fix it by replacing run_caddy method in wp-content/plugins/caddy/caddy.php by :
function run_caddy() {
if (!isset($_GET[‘et_fb’])) {
$plugin = new Caddy();
$plugin->run();
}
}
That deactivates the module when divi builder is on (we don’t need it to be active when builder is on).
