Including this hook now redirects the front-end visitor to the wordpress login form (?)
As far as I can see from the documentation, it’s the acf/pre_save_post hook I need as this was made with front-end submissions in mind.
Just can’t get it to save the taxonomies!
It worked on a previous version of WordPress (4.5.4), but now it doesn’t since I upgraded to 4.7.
Any more suggestions?
