Customization Broken: gives error instead

Every time I try to click ‘customize’ or Appearance> Customize from the dashboard I get this error:

Fatal error: Call to undefined method WP_Customize_Manager::register_section_type() in /home/content/46/8819846/html/wp-content/themes/sydney/inc/upsell/class-customize.php on line 68

Hello,

Can you please try to deactivate all your plugins except recommended and see if it helps?

Kind Regards, Roman.

I tried this and it didn’t help! same error.

What WP version are you using?

version 4.1.13

You should really update. Current WP is 4.6.1.

this worked! thanks, vlad :slight_smile:
