We use core drupal's Poll module where admin can add options to the polls by clicking "Add option" & at the same time they can remove the options by clicking "Remove option"
Here's our problem,
On Second Submit of AHAH Form by clicking "Add options" we are getting these warnings:
warning: array_shift() [function.array-shift]: The argument should be an array in ...
warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback....
Can some one suggest the possible changes to be done to avoid these errors.
We are using Authcache module with APC . The environment consists of 3 servers. each running its own apc instance. and the servers are behind a load balancer.
