I like to keep my the plugins and wordpress versions up to date on the various blogs I manage. Sometimes though, the update process doesn’t go quite so smoothly, especially when updating the WordPress core.
If an update fails, you’ll be presented with a maintenance screen and no way of accessing your site and will only see the maintenance screen.
The solution? Well it’s pretty easy actually.
1. Log in to your site’s FTP connection
2. Delete the “Upgrades” directory (/wp-content/upgrades/)
That’s it 🙂
