Hi,
I am receiving the error N2WordpressAssetInjector::output_callback’ on https://manouchejazz.co.uk - the site is clean and I have disabled plugins but still receive the error.
I am using WP Rocket but have disabled and enabled it. I use WP Rocket on my other sites where I have your excellent plugin and it does not cause a problem at all.
I have read other posts in this forum who have had this problem and I cannot track the error down on my site.
Any advice to solve this gratefully received.
Best wishes,
Stephen
