During the WordPress upgrade process, if you refresh the page or close the page, the Wordpress upgrade may fail. This problem may occur during the next upgrade. For example, I refreshed the page a few days ago, and when I upgraded Wordpress again, Wordpress always prompts "another update is in progress ".
This is because when you upgrade Wordpress, Wordpress adds the core_updater.lock record in the wp_options table of the database. If the Wordpress upgrade is interrupted halfway, this record will be left in the database. When Wordpress detects the existence of this record during the next upgrade, it returns "another update in progress ". You can solve this problem by using the following methods:
Use phpmyadmin or navicat to manage the Wordpress Database. In the wp_options table, locate and delete the core_updater.lock record.
All right, you only need to delete this content during the upgrade process. Of course, do not click the upgrade repeatedly during the upgrade process.
