Hi @Nitruc
Thanks for the follow up. Perhaps the solution is to remove the ‘wpautop’ filter from the formating of the WYSIWYG value.
Normally, this would be done via:
remove_filter ('the_content', 'wpautop');
But ACF uses a custom filter called ‘acf_the_content’, so try this in your functions.php file:
remove_filter ('acf_the_content', 'wpautop');
Hope that helps.
Thanks
