keeps happening on one site im afraid i dont know why

That's an odd one. I'm not quite sure why wp_get_current_user() wouldn't be available at that point yet. Thanks for including the full backtrace.

Could you let me know the full list of plugins installed on that site, so I can try to reproduce on my end?

Also, is this happening when deactivating a specific plugin from the Plugins menu?

That's an odd one. I'm not quite sure why wp_get_current_user() wouldn't be available at that point yet.

That part is easy enough to explain: the function is defined in wp-includes/pluggable.php, which isn't loaded until after plugins are loaded. The stack trace is happening during the load of the WooCommerce Bulk Discount plugin.

Where I get lost looking at this trace is here:

#5 /home/vwf08ule8jdp/public_html/radicalsupplements.com/wp-admin/includes/.inc(18): deactivate_plugins()
#6 /home/vwf08ule8jdp/public_html/radicalsupplements.com/wp-admin/includes/plugin.php(2619): include_once('/home/vwf08ule8...')
#7 /home/vwf08ule8jdp/public_html/radicalsupplements.com/wp-admin/includes/plugin.php(2619): {closure}()

Which version of WordPress is being used here? Do you have custom modifications to these files?

Thanks for your reply Anomix, its 6.1.1 and nothing custom going on as you can tell im not much of a web developer, i simply installed wordpress, elementor, woo commerce and a few other plugins and made a quick site. Its probable that a clean FTP upload of WP files will fix but i really wanted to get to the bottom of why its happening as its about the 5th time this year

Thanks for the info, knowing the version of WordPress in use helps.

The stack trace shows execution at line 2619 of wp-admin/includes/plugin.php, but when I look in the WordPress source for 6.1.1, that file only has 2588 lines. Then the trace also shows execution in a file named wp-admin/includes/.inc, which doesn't exist at all in the WordPress source.

While I can only guess without seeing the code in those files, it seems like that added code is trying to deactivate the Jetpack plugin if it finds it enabled, and only happens to raise an error because that WooCommerce Bulk Discount plugin happens to be causing the code to run too early during WordPress's initialization.

Closing this for now because of the lack of activity on this. We can always reopen in the future if needed.
