Symptoms
The “Internal server error” warning message appears in the various application pages, pages without performance data or corrupted pages are displayed, or page cannot be loaded issues might be encountered after the application is updated to a newer version.
Problem
The various issues that occur after upgrading the application to a new version could be manifested in various ways, and some of the most common symptoms are listed here.
Internal server error and data not displayed in charts
The page cannot be loaded completely
Corrupted pages
Cause
The cause of those problems is the way web browsers are handling the cache. After the upgrade of the application, the browser still tries to use and call the pages he keeps stored in the cache, but changes made in a newer version prevents the browser to complete the page loading correctly, which causes the described issues.
Solution
To resolve the problem, clear the cache in the web browser used with the application. Since it is not possible to predict whether and where the problem will occur after updating to the newer version, it is advisable to perform browser cache clearing after every application update to prevent potential issues.
