I’m having more problems with the theme …

1) In the options of the theme, I can not change ON / OFF in the options. I click on the button and nothing happens.

2) Error in the options page:
Mailchimp List Id

Fatal error: Uncaught error: Call to undefined function painting_mailchimp_list_ids () in /home4/ajapainting/public_html/wp-content/themes/painting/framework/theme-options/general.php:106 Stack trace: # 0 / home4 / ajapainting / public_html / wp-content / themes / painting / framework / theme-options / settings.php (69): require_once () # 1 /home4/ajapainting/public_html/wp-includes/class-wp-hook.php(286): # / home4 / ajapainting / public_html / wp- includes / plugin.php (453): WP_Hook-> do_action (Array) # 4 /home4/ajapainting/public_html/wp-admin/admin.php(224): do_action (‘appearance_page …’) # 5 / home4 / / ajpainting / public_html / wp-admin / themes.php (10): require_once (‘/ home4 / ajapaint …’) # 6 {main} thrown in / home4 / ajapainting / public_html / wp-content / themes / painting / framework /theme-options/general.php on line 106

3) Nothing happens when I click on the left side menu.

I think they should test the theme better, before launching it, because I had a problem installing it, needing an intervention from the author (which should not be necessary) and now more problems in use.
