Hello,

I juste updated ACF but when logged into the wordpress dashboard I receive this error when I try to access ‘Plugins’ or ‘Update’:

Fatal error: Call to undefined function wp_json_encode() in /home/…/wp-content/plugins/acf-repeater/acf-repeater-update.php on line 265

How do we fix this?
Thank you for your help,

Thib

Hi @thib

Is it possible that you are running an outdated version of WordPress?

If so, please deactivate ACF, update WordPress and then activate the plugin once again.

Thx James,

Effectively, so I removed from my FTP plugin, updated WordPress and reinstalled the ACF folder: perfect it’s nickel!
