Warning:Can only flip STRING and INTEGER values!

I've found the same and in my case is solved patching og.module as: http://drupal.org/node/1368930 says.
If not... get your hands dirty and do some backtraces.

The error probably happens when Statuses calls og_is_member() in statuses.context.inc lines 234, 243, and 248 if og_get_group_ids() returns an empty array. The solution should just be to check if we get an empty array before calling og_is_member() in those cases.

came up with a patch based on IceCreamYou's suggestion. It doesn't really change much. But still attaching the patch as it is a good idea to check whether array is empty or not before passing it in a function.

Use spaces instead of tabs, and all non-ternary conditions should be wrapped in curly braces. Other than that this looks fine

Wrong spacing. Each block level should be indented exactly 2 spaces from its parent block

There needs to be a space between language constructs and parenthesis, i.e. if (condition) not if(condition). This problem occurs several times

the body of a block should be indented

Sorry for being a little careless last time. Hope this does it.

Committed patch in #7 to dev. Thanks!
