This article describes how to resolve the issue in Adobe Experience Manager (AEM) LTS SP03 where the file upload popup does not appear when selecting ‘File’ from the Create button in the Asset screen after switching from a customized environment.

Description description

Environment

  • Adobe Experience Manager (AEM) LTS SP03
  • On-Premise Software

Symptoms

  • When selecting ‘File’ from the Create button in the Asset screen, the file upload popup does not appear.
  • The issue occurs after operating in a customized AEM environment and then starting the standard AEM environment.
  • No error messages are displayed.

Steps to reproduce

  1. Create an AEM environment from the standard installation package.
  2. Navigate to Assets > Files.
  3. Select ‘File’ from the Create button.
  4. Observe that the file upload popup does not appear.

Cause

Cache artifacts remaining after operating in a customized AEM environment affect the behavior of the standard AEM environment. This is not a product defect in the standard AEM LTS SP03.

Resolution resolution

Follow the steps below to resolve the issue.

  1. Clear the browser cache and cookies before starting the standard AEM environment.
  2. If using multiple AEM environments (customized and standard), ensure that the browser session is fully reset between environments.
  3. Restart the browser after clearing cache to avoid session artifacts.
  4. If the issue persists, verify that no customizations or hotfixes are interfering with the standard environment.

After completing these steps, attempt to use the Create button in the Asset screen to confirm the file upload popup appears as expected.
