WordPress Update – 504 Gateway Time-out

Looking to update WordPress to the latest version, I clicked on update, but after a while I received the following error:

504 Gateway Time-out
The server didn't respond in time.

So what to do?

Sometimes with WordPress updates its worth being patient. I’ve seen errors which when returning to the site have cleared. In this case the same was true. I visited the site direct, public view. All was well, but an update was marked as outstanding. It then went to the admin with the WordPress core update pending.

So I refreshed the browser tab with the with the 504 gateway error. And low and behold all was well the update was completed.

One moment of hesitation – a single update was still being shown in the black top bar. But all was well it was a plugin which needed to be updated, based on the newer version of WordPress.
