Upgrading Civi from 5.15.1 to 5.21 can be a complex process, and encountering issues during the upgrade process is not uncommon. One such issue is when the "Upgrade the database" URL does not load the upgrade screen, causing a roadblock in the upgrade process. In this article, we will discuss the possible causes of this issue and provide a step-by-step solution to resolve it.

Understanding the Issue

The "Upgrade the database" step is a critical part of the Civi upgrade process. It involves upgrading the database schema to the latest version, which is essential for the smooth functioning of the Civi application. However, when the URL for this step does not load the upgrade screen, it can be frustrating and time-consuming to resolve.

Possible Causes

There are several possible causes of this issue, including:

  • Incorrect URL: The URL for the "Upgrade the database" step may be incorrect, leading to a 404 error or a blank page.
  • Database Connection Issues: Problems with the database connection, such as incorrect database credentials or a failed database connection, can prevent the upgrade screen from loading.
  • Civi Configuration Issues: Incorrect Civi configuration settings, such as an incorrect database name or a missing database prefix, can cause the upgrade screen to fail to load.
  • WordPress Configuration Issues: Issues with the WordPress configuration, such as an incorrect WordPress URL or a missing WordPress database prefix, can also cause the upgrade screen to fail to load.
