Update: I was able to prevent the Fatal Error mentioned above if I modified admin.php around line 924 …

from:

list( $columns, $hidden ) = $wp_list_table->get_column_info();


to:

if (is_callable(array($wp_list_table, 'get_column_info')))
list( $columns, $hidden ) = $wp_list_table->get_column_info();
else
$columns = $hidden = array();


Practically speaking, this prevents the $columns and $hidden variables from being set, but I’m not sure what this section of code does anyway. Is there a better workaround?

Possible workaround or clue to fixing this problem….

I too recently found all my CPT-onomy checkboxes being disabled as described above. (This was a new install, so I don’t know if it was version-related.) After trying a bunch of different things — looking for plugin conflicts, manually editing the plugin code — I finally discovered that the glitch seemed to be related to the SLUG of the custom post type that was being registered as a CPT-onomy.

My custom post types that were set up with a HYPHEN in their slugs DIDN’T WORK as CPT-onomies (their checkboxes were disabled). When I edited my CPTs so the slugs had NO HYPHENS (a-z only), the checkboxes worked.

Hope this helps!

Thanks … that did the trick!

… And it seems like I’m finally getting everything working again with your plugin.
