Update to 3.9 issue

site is villagehomepub.com

Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– re-uploading all files & folders – except the wp-content folder and the 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.

– running the upgrade manually via wp-admin/upgrade.php

Went down the plugin.old route but just got following when went to villagehomepub.com/wp-admin

Site is up but without any plugins.

How do I running the upgrade manually via wp-admin/upgrade.php

Thank you for your time

All sorted, shut down all plugins and uploaded 3.9 via FTP.

Just got to turn on plugins one by one to see which pesky little number was causing the problem.
