Make sure that you delete the old copies of files & folder before uploading the new ones. * – running the upgrade manually via wp-admin/upgrade.php * [fpats](https://wordpress.org/support/users/fpats/) * (@fpats) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677687) * Fixed here, was the theme.

The fix will be included in 4.6.1 * You could apply[ the changes](https://core.trac.wordpress.org/changeset/38277) from there on your site to see if it fixes the issue, i.e. add `if ( is_wp_error( $object_terms ) ) { return $object_terms; }` on that one line in `wp-includes/ taxonomy.php`. _Not_ `wp-includes/functions.php`, but those two are related. * Feel free to test this change and reply on the ticket if the change fixes your issue. * [bkimbley](https://wordpress.org/support/users/bkimbley/) * (@bkimbley) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677759) * The change didn’t work for me, although I wasn’t able to find the second file listed. I made the change only to taxonomy.php. Where’s the other file located? * [bkimbley](https://wordpress.org/support/users/bkimbley/) * (@bkimbley) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677764) * My problem was that apparently during the update, the index.php file in the root directory had it’s permissions changed to 666, and that’s too open for WordPress to work. I changed it to 644, and poof, back on line. * [bkimbley](https://wordpress.org/support/users/bkimbley/) * (@bkimbley) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677767) * The site itself is back on line, still can’t get access to admin… * [bkimbley](https://wordpress.org/support/users/bkimbley/) * (@bkimbley) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677770) * Last update – turns out that many of the files (almost all) in the wp-admin directory had permissions changed to 666. Changed them all to 644, and I’m now able to get into the WordPress backend. * Thread Starter [kamal5](https://wordpress.org/support/users/kamal5/) * (@kamal5) * [9 years, 7 months ago](https://wordpress.org/support/topic/wordpress-error-after-update-46/#post-7677771) * hey guys thanks for feed back .. i had solved ..
