I have tried turning off all plugins, and updating still fails:
Fatal error: Uncaught Error: Call to undefined method WP_Error::has_errors() in /homepages/28/d66119722/htdocs/Alliedprofessional/wp-admin/includes/file.php:1504 Stack trace: #0 /homepages/28/d66119722/htdocs/Alliedprofessional/wp-admin/update-core.php(501): WP_Filesystem(true, ‘/homepages/28/d…’, false) #1 /homepages/28/d66119722/htdocs/Alliedprofessional/wp-admin/update-core.php(711): do_core_upgrade(false) #2 {main} thrown in /homepages/28/d66119722/htdocs/Alliedprofessional/wp-admin/includes/file.php on line 1504
