Vote Up and Vote down Issue

Hi Rahul,

1.When i vote up to any Question/Answer after that ideally “vote up buttton” should be disable, but instead of that “vote down button” disappearing.

2. I want to increase views count only once from every IP, how i can achieve that?

3. how i can assign question to all parent category of selected category?

4. how i can overwrite theme/plugins files.

Actually I did as you mention in any other answer, but it’s not working

I copied files from

wp-content/themes/askbug/includes/hooks.php

to

wp-content/themes/askbug-child/includes/hooks.php

but nothing happening.

Please guide me which files and how i can overwrite? also need solution for the plugin files.
