Do you ever wonder why a page loads incorrectly when using CA PPM? If you have, this is a likely case of the corrupted cache.
A browser temporarily stores files that make up a webpage locally, because it is faster to retrieve and display information from the local hard disk, rather than making a full request from the server.
For example, every time the client browser makes a request for an image, the browser can retrieve this image from the local disk, which is faster than downloading it from the server.
During this process, the caches (locally stored temporary files) can become corrupted from events such as bad or incomplete page loads. If the webpage rendering is intermittently or
inconsistently loading, take the following steps to rule out a caching issue.
In CA PPM, it is best to take both steps in order to perform a complete cache flush to resolve the issue.
STEP 1: Clear the browser cache.
For Microsoft Internet Explorer® browsers,
Go to IE > Tools > Internet Options > General tab >
In the 'Browsing history' section > click Settings button >
a. Select radio button(Every visit to the page);
for performance issues, select radio button(automatic);
b. Click view objects; delete what is listed in the window
c. Click view files; delete what is listed in the window
d. Close out of all IE windows.
e. Check if the problem persists

Another option is to download and install Fiddler to clear the caches/cookies via:

The issue should be resolved, after performing the above.
If the issue is not resolved, please open a case before proceeding to the following steps.
STEP 2: Clear the CA PPM Server cache.
a. Login to CA PPM application as an admin user
b. Modify the URL field to: http://<svr>/niku/nu#action:security.caches
c. Click Caches tab, click FLUSH ALL button
d. Click Groups tab, click FLUSH ALL button
e. Logout
f. Login and check if problem persists.
STEP 3: Restart CA PPM app services.
If the problem persists when both steps above are taken, perform a rolling restart of all APP services.
