Title: Fatal error: Call to undefined function wp_removable_query_args() Last modified: August 30, 2016 --- # Fatal error: Call to undefined function wp_removable_query_args() * [MSingAste](https://wordpress.org/support/users/msingaste/) * (@msingaste) * [10 years, 5 months ago](https://wordpress.org/support/topic/fatal-error-call-to-undefined-function-wp_removable_query_args-1/) * Attempt to upgrade to 4.4 was hanging. Refreshed to try it again. Removed .maintenance file. Now get the following when trying to access the Dashboard: * Fatal error: Call to undefined function wp_removable_query_args() in /homepages/ 25/d161191648/htdocs/wsb4027312702/blog/wp-admin/includes/misc.php on line 900 * Disabled plugins using phpMyAdmin method and deleted and replaced all but wp- content and wp-config.php from download of WordPress. No joy. 🙁 Please help!

After replacing just function.php the error changed to the following: * Fatal error: Call to undefined function wp_installing() in /homepages/25/d161191648/ htdocs/wsb4027312702/blog/wp-includes/functions.php on line 1354 * Tried in two different browsers. * Thread Starter [MSingAste](https://wordpress.org/support/users/msingaste/) * (@msingaste) * [10 years, 5 months ago](https://wordpress.org/support/topic/fatal-error-call-to-undefined-function-wp_removable_query_args-1/#post-6866604) * Oh, and after replacing that function.php file my blog is no longer viewable at all! Not just the dashboard that’s broken! * Thread Starter [MSingAste](https://wordpress.org/support/users/msingaste/) * (@msingaste) * [10 years, 5 months ago](https://wordpress.org/support/topic/fatal-error-call-to-undefined-function-wp_removable_query_args-1/#post-6866606) * Tried downgrading to the previous version.

Oops! Now successfully downgraded with access to blog and dashboard. I’ll count my blessings and stay here for awhile.

I know upgrading is the last thing you want to think about after having an issue like that, but it’s always best practice to keep up with the latest versions. I would recommend backing up your database and files, reviewing the procedures for [updating WordPress](https://codex.wordpress.org/Updating_WordPress), and trying again. Feel free to ask any questions you may have on the procedure. Good luck!
