Woocommerce Plugin causes crash in customization panel

When I activate Woocommerce plugin (version 3.3.3), and then go to Apperance -> Customize in the WP admin panel, the Customize panel site crashes. I’ve tried deactivating all plugins and reactivating one by one. It’s only Woocommerce that causes the customize panel to crash.

I tried changing theme from Sydney Pro to a wordpress theme Twentyseventeen, and with Woocommerce plugin activated I had no problems loading the Customize panel. So I think it has something to do with Sydney Pro.


I couldn’t recreate this issue on my local Sydney Pro install.

You can try to rebuild your website in a staging environment or locally and see if it works as it should (then you will be able to move rebuilt website to production environment). Please remember about importance of regular full site backups (files and database):
