# SmartConsole's "Logs & Monitor" tab does not show logs, "The session has expired. please try to refresh the view" message appears

## Product
Security Management

## Version
R81.20

## Last Modified
2025-03-20

## Symptoms
- After installing R81.20 Jumbo Hotfix Take 90 or 92, the **Logs & Monitor** tab in SmartConsole does not display logs, and the page remains blank. The following message appears:

`The session has expired. Please try to refresh the view.`

**Additional Observations**:

- The _fw.log_ file is growing, indicating that logs are being recorded.
- The Log Indexer is indexing the logs. The _log_indexer.elg_ file shows `Sent  Current: ###`
- The _/opt/CPrt-R81.20/log/RFL.log_ file contains these lines:

```
    ERROR [pool-1-thread-3]
    com.checkpoint.rfl.exceptions.DefaultUncaughtExceptionHandler.uncaughtException:3 - uncaught
        exception from thread id: [68], name: [pool-1-thread-3]

java.lang.NoSuchFieldError: org/apache/cxf/message/Message.CONTENT_TRANSFER_ENCODING
    ```

## Cause
A deprecated _.ja_ r file causes a code dependency issue.

This problem was fixed. The fix is included in:
