fix undefined array keys in category_page_renders function

[bianqui149]

Problem

The function category_page_renders was throwing an error: Undefined array key "v3_widgets_enables" and Undefined array key "v2_widgets_enables". This issue occurred when the $settings array did not include these keys, leading to unexpected behavior or crashes.

Solution

• Added checks using isset() to ensure the keys v3_widgets_enables and v2_widgets_enables exist before attempting to access them.
• Applied !empty() to verify that the values are not null or empty before performing actions.
• This prevents the function from attempting to access non-existent array keys, ensuring smoother execution without errors.

Testing

• Manually tested with different $settings configurations to ensure the function behaves as expected and no longer throws the error.

Impact

This fix ensures that the category_page_renders function handles cases where the $settings array might not contain the expected keys, improving overall stability.
