I have just installed a fresh version of WP which I have turned in to a network install (using the instructions found here).

All seemed to be going well, and I was able to add a new site successfully, however I am experiencing issues with listing/adding users.

When I click on the Users menu item the list table gives the following warning -

Warning: array_keys() expects parameter 1 to be array, boolean given in {my-dir}\wp-admin\includes\class-wp-users-list-table.php on line 307

This line is - $editable_roles = array_keys( get_editable_roles() ); - the issue is that get_editable_roles() is ruturning false.

The same problem also occurs when I try to add a user, although the warning is at a different location -

Warning: array_reverse() expects parameter 1 to be array, boolean given in {my-dir}\wp-admin\includes\template.php on line 843

I've tried the obvious, deactivating all plugins (I'd added one) and switching to the default theme, but the warnings still remain.

Looking at get_editable_roles() I can see that the global $wp_roles->roles is empty, although $wp_roles->role_objects is correctly populated. From here, I don't really know where to go next.

Can anybody please suggest how I may fix this problem?

    Which plugin did you installed? I heard about some plugins be responsible of this error. Try to make the fresh install again without installing any plugin. – cybmeta Dec 30 '14 at 15:43
  • It was a custom plugin that creates a new post type and two new taxonomies (I wish to use this on multiple instances within the network, hence the need for a plugin rather than it being within a theme/child theme). No posts or terms had been created using them though, and sadly disabling it made no diference. Thanks. – David Gard Dec 31 '14 at 10:22

In the DB, the wp_user_roles option in wp_options was empty. I copied the value from the same option in wp_2_options, as I had already added another blog.

Also, every user from the original blog (it was up and running before being changed to a network) had nothing listed against both the wp_capabilities and wp_user_level options in wp_usermeta. Because of this, the get_editable_roles() function was failing and in turn causing the errors listed above.

To fix this problem, for each user on the original blog, I copied the entries for the relevant user levels from the data stored under wp_2_capabilities and wp_2_user_level.

    I have the same issue and can't figure out how to fix it. I have checked my wp_x_options tables and they have values set for wp_x_user_roles row. And my wp_usermeta table has a wp_capabilities row for most users. I need to dig deeper into the schema to see exactly how it fits together. – Tom May 8 '15 at 18:24
  • Trick for me was renaming the wp_user_roles to wp_x_user_roles - wordpress.stackexchange.com/questions/11725/… – benedict_w Jul 14 '15 at 7:22
