Admin panel taxonomy terms listing results in a fatal error

[magadanski_uchen]

I installed WordPress 4.0 and going to a taxonomy terms (such as categories at /wp-admin/edit-tags.php?taxonomy=category) I get the following fatal error:

Access level to WP_Terms_List_Table::get_columns() must be public (as in class WP_List_Table) in \wp-admin\includes\class-wp-terms-list-table.php on line 456

I can't reproduce in my local checkout, and WP_Terms_List_Table::get_columns() is public in my local install.

To confirm, this is a stock install with no plugins and Twenty Fourteen active? Can you look into why the method might be something other than public?

I am fixing these now - tons of mismatches in List Table subclasses

[SergeyBiryukov]

Could not reproduce neither on PHP 5.2.4 (minimal required version) nor on 5.2.17.

WP_Terms_List_Table::get_columns() is public, see [29118]. Make sure you have that file updated.

In 29137:

Fix mismatches in access modifiers for WP_List_Table + subclasses.

Fixes #28843, #28879.
