3.9.2 to 4.0 update issues

– try resetting the plugins foldervia FTP or SFTP or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).
– If all the above steps do not resolve the issue, try MANUALLY re-uploading all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. Read the Manual Update directions first!
– running the upgrade manually via wp-admin/upgrade.php
– BTW, if you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong. It’s a great safety net.

Hi Tara,

Thanks for your insights, unfortunately this didn’t fix the issue as I had already tried those steps.

It seems that the problem was in my varnish cache, for some reason after disabling varnishd and setting my apache config back to listen on port 80, when I accessed wp-admin, it informed me I needed a DB update and went about it perfectly.

Not sure why varnish was playing up but there you go.

Cheers,
Daryll

Glad you got it sorted ??
