Remarketing list(s) disabled for use with Google AdWords
The reason you're experiencing problems is two fold.
The first is because you have the Google Analytics tracking code added to your site twice. It should be only added once.
The second problem, the remarketing problem is similar. You have MULTIPLE implementations of it. You only need one.
I would recommend getting a webmaster to help you paste the code into your website only once.
1- I removed the duplicate analytic code.
2- Its wordpress site, was trying to add remarketing in its Footer.php or header.php, everything it was showing error - Code found outside of <body> , Don't know why when we can paste code on header or footer to show it on all pages.
So, I decided to remove remarketing code and create the analytic re-marketing list and updated the code as mentioend here - https://support.google.com/analytics/answer/2444872?hl=en&utm_id=ad
can you please check and confirm analytic code once again.
