 In a multi sites worpress setup environment, there are times where
 get_options would cause illegal string offset warnings.

 The issue is caused by $notoptions that can contain a string from
 get_get_cache call.
 To avoid the potential warning errors, we should check to make sure
 $notoptions variable is an array before trying to assign array indexed
 value to it.
