Hi There,
I can see this error:
Mixed Content: The page at 'https://live-up.co/category/ot-stressa/' was loaded over HTTPS, but requested an insecure script 'http://live-up.co/wp-content/plugins/ultimate-popup/js/ppm-side-popup.js?ver=1'. This request has been blocked; the content must be served over HTTPS.
Please add this in .htaccess file in your root directory:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
Hope it helps.
