Title: WP_Error code after update to 4.6 Last modified: September 1, 2016 --- # WP_Error code after update to 4.6 * [lisadavis](https://wordpress.org/support/users/lisadavis/) * (@lisadavis) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/) * The update to 4.6 was applied to my site yesterday and since then only the home page will load properly. When trying to view any other page, this message is displayed. * FATAL ERROR: Cannot use object of type WP_Error as array in /HOME/TOWERSEY/PUBLIC_HTML/ WP-INCLUDES/FUNCTIONS.PHP on line 3511 * Is there anything I can do about this please? * Lisa * [http://www.towerseyfringe.co.uk](http://www.towerseyfringe.co.uk) Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/page/2/?output_format=md) [→](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/page/2/?output_format=md) * [Jacob Peattie](https://wordpress.org/support/users/jakept/) * (@jakept) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/#post-7678652) * Line 3511 of includes/functions.php is a function that’s used inside many others, so I think the actual issue is occurring somewhere else. Can you try deactivating plugins one by one and checking if the issue goes away. If it does the last plugin you deactivated might have some compatibility issues with 4.6. * Thread Starter [lisadavis](https://wordpress.org/support/users/lisadavis/) * (@lisadavis) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/#post-7678719) * I have disabled all the plug ins, one by one, and checked to see if the problem is still there. After having disabled all the plugins, I still have the same problem. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/#post-7678730) * Have you tried: * – deactivating **all** plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s). * – switching to the default theme to rule out any theme-specific problems. * – [resetting the plugins folder](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems. * – re-uploading all files & folders – **except** the wp-content folder and wp- config.php & root .htaccess files – from a **fresh** download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. * [vmabril](https://wordpress.org/support/users/vmabril/) * (@vmabril) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/#post-7678804) * I’m having a similar issue that popped up as soon as the update kicked in. I already turned off the plugins and that doesn’t seem to make a difference. The website is up but many of the posts are not, and they’re all displaying this same message: * **FATAL ERROR: Cannot use object of type WP_Error as array in /xxxxx/xxxxx/PUBLIC_HTML/ WP-INCLUDES/FUNCTIONS.PHP on line 3511 * I do see that some suggestions are to change the theme, but I can’t do that since our site is running on a custom theme. I’m thinking the best option would be to try and rollback to the prior version, but the problem is that our site doesn’t have a backup. * Can anyone help please?

You can suspect a similar origin in more cases. Hope this helps.

It is much appreciated. * The person who has access to the files and folders says that they all look “OK”. I have again disabled all plugins but it made no difference. I am at a loss to know what to do. This site is for a charitable event happening this weekend and last year (our first year) most online ticket sales were made in the week running up to the event. * Lisa * [http://towerseyfringe.co.uk](http://towerseyfringe.co.uk) * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp_error-code-after-update-to-46/#post-7678991) * > The person who has access to the files and folders says that they all look “ > OK”. * Irrespective of how the files “look”, ask this person to re-upload all files & folders – **except** the root wp-config.php & .htaccess files and the wp-content folder – from a **fresh** download of WordPress.
