[Backend] Crashing when trying to view the addons screen of Woocommerce

Hey guys!

I am getting an error when I click on the subscriptions tab of Woocommerce.

I do not have any PHP snippets and the problem still persits.

I believe the issue could come from the filter that adds the body class to the woocommerce “Subscription” tab on the Admin area for the addons.

I can’t troubleshoot because the stack trace does not reveal that your code is at play here, but by a process of elimination, deactiving custom codes fixes the issue. The issue can be replicated on other sites on live servers.

I do not think it is a rush to fix this because the tab is an admin tab for addons for woocommerce and can be avoided.
