## Symptoms

- Users do not receive push notifications when legacy MAB portal is used, while mail through Capsule Workspace is functional.

## Cause

The PHP file 'RPCClientFactory.php' is missing from the Mobile Access Blade's legacy portal UI file structure. This prevents flows involving this file from working.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 82
* [Jumbo Hotfix Accumulator for R81](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81/Default.htm) starting from Take 79

If you choose not to upgrade, use this workaround:

The missing file of the legacy portal can be replaced by copying it from the existing new portal:

`# cp $CVPNDIR/phpincs/RPCClientFactory.php $CVPNDIR/phpincs_legacy/RPCClientFactory.php`
