I upgraded to version 2.1.2 and then started seeing this error in the back end:
Warning: array_map() [function.array-map]: Argument #2 should be an array in /website/wp-content/plugins/custom-field-template/custom-field-template.php on line 294
When I try to save a page post I get:
Warning: Cannot modify header information - headers already sent by (output started at /website/wp-content/plugins/custom-field-template/custom-field-template.php:294) in /website/wp-includes/pluggable.php on line 876
Downgrading back to version 2.1.1 removes the errors.
