The full warning given is:
'Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'wp_cufon_delay' was given in F:\wp-includes\plugin.php on line 339'
I've followed the instructions, everything seems right but I get this error even on 2 different WP instances (both version 2.9.2).
Anyone seen this before and know how to fix it?
