Hi Daniel, thanks for your reply. I checked both the header.php and the footer.php. I could not find any code like you suggested in either file (<script src="".)
I’d love to fix this.
I have only manually added the Facebook comments code into header.php. When I remove the code the issue persists. This code is here: https://developers.facebook.com/docs/plugins/comments/
Here is a list of plugins that I have installed:
a3Lazy Load – tried to disable, but the issue persists
Black Studio TinyMCE Widget
CloudFlare
CloudFlare Flexible SSL
Contact Form 7
Contact Form 7 MailChimp Extension
EWWW Image Optimizer
Google AdSense
Google Analytics Dashboard for WP
Google Captcha (reCAPTCHA) by BestWebSoft
Invisible Optin
Jetpack by WordPress.com – tried to disable, but the issue persists
Limit Login Attempts
MailChimp for WordPress Lite
MaxButtons
Optimize Database after Deleting Revisions
Shareaholic – tried to disable, but the issue persists
Simple Image Sizes
Stop Spammers Spam Control
Use Google Libraries
WordPress SEO
Maybe I need to bark up some other tree to get this fixed but I do not know where to turn to at the moment because all works if Popup Maker is inactive and it does not work if Popup Maker is active.
Thanks for your attention
Beat
