[1.8] Opigno core - Ajax autocomplete bug on node create

When creating a new node. The autocompletes give a ajax error. Introduced with core function opigno_og_context_handler.

"Related to your first post. Regarding the ajax error. This bug was recently introduced, and it is only triggered on a node add, not when editing a node. Instead of changing the widgets of the fields, you can edit the opigno.module, inside the function opigno_og_context_handler(), change the line

if (og_is_group('node', node_load(arg(6)))) {

to

if (is_numeric(arg(6))&&og_is_group('node', node_load(arg(6)))) {

We will include this on our next release. Thank you for your feedback. Best regards"
