Hello, When I click on 'Post to Forum' in an out-of-box installation of Drupaligg, I get the following warning:

warning: array_merge_recursive() [function.array-merge-recursive]: Argument #2 is not an array in /opt/lampp/htdocs/drupaligg/modules/node/node.module on line 1990.

How do I fix this and what is the error?

Thanks,

Gaurav
