Automatic update failing_Several methods for manually updating WordPress version

WordPress is an open source website building program, which will continuously introduce new versions over time. For the safety of the website, we also need to update and upgrade WordPress. This article introduces several WordPress update methods, including automatic update and manual update. Details are as follows:

Automatically update WordPress

Automatic update of WordPress is very simple. Click the update button directly in the background. If you use a foreign virtual host, you usually do not need to click the update button. When there is a new version, the system will automatically update you to the new version.

Of course, your virtual hosting company may not enable the automatic update function for you, so you can click the update button once.

However, due to network problems, domestic servers often fail to update. At this time, we need to update manually to solve this problem.

Failed to update WordPress, prompting "Another update is in progress"

If the automatic update of WordPress fails, it can only be updated manually. The most common failure prompt for updating WordPress is“ Another update is in progress ”

When you encounter this prompt, you can search online. The basic solution is to let you go to the database to delete a core_updater.lock table file.

The basic online method is to let you enter the website database (via phpmyadmin or ssh, such as command mode)

Search core_updater.lock in the wp_options table to find a value. Then delete it and update it again.

But, This method is not 100% effective for domestic hosts , because the speed of domestic hosts accessing the WordPress server is not stable, It is likely that the download will not succeed, leading to the upgrade failure, So you need to upgrade WordPress manually at this time.

in addition If the automatic update of domestic servers fails, it is also easy to have white screens or error reports 。

At this time, you only need to manually update once again to solve the problem.
