Hello all,

Recently i got an error on the tools page (also after reverting to older versions):
Notice: Undefined index: param in /var/www/html/wp-content/plugins/advanced-custom-fields-pro/includes/compatibility.php on line 397

I tried re-enabling the plugin, installing older versions but with no succes. The error prevents me from exporting my field groups.

Does anyone have an idea on how to fix this?
