I have a problem in back-office,
when I go in posts/categories on top of the screen it prints a notice:
“Notice: Trying to get property of non-object in …myroot/wp-content/plugins/advanced-custom-fields/core/controllers/location.php on line 343”
and then when i update a category description for example it prints an error:
“Warning: Cannot modify header information – headers already sent by (output started at …myroot/wp-content/plugins/advanced-custom-fields/core/controllers/location.php:343) in …myroot/wp-includes/pluggable.php on line 876”
