Hi @sem90
Thanks for the clarification. The setting for ‘Run filter “the_content”’ has been removed in v4 as it caused many issues such as the one you are describing.
Basically, the ‘the_content’ filter should only be run once on a page, and running this multiple times can caused various errors with 3rd party plugins and themes.
Your options are to upgrade to ACF v4, or disable the option and add this code to your template:
<?php do_shortcode( get_sub_field('wysiwyg_field_name') ); ?>
Thanks
