You added this code to your theme's functions.php to register a sidebar:
register_sidebar('name' => 'Blog Sidebar', 'id' => 'blog-sidebar');

But the sidebar does not appear in the Widgets admin area. What is the error?
AThe sidebar name cannot contain spaces
BThe function call is missing an array around the arguments
CThe function name should be <code>add_sidebar</code> instead of <code>register_sidebar</code>
DThe sidebar ID must be numeric, not a string
Step-by-Step Solution

    Wrapping the arguments in array() or [] is necessary for correct registration.
  3. Final Answer:

    The function call is missing an array around the arguments -> Option B
  4. Quick Check:

    register_sidebar() needs array argument [OK]
Quick Trick: Always pass an array to register_sidebar() [OK]
Common Mistakes:
  • Passing arguments directly without array
  • Using wrong function names
  • Thinking sidebar ID must be numeric
