Hello,
 

In the latest WHMCS update (version 8.13.1), I can no longer find the username and password details for my clients. How can I customize or update these credentials when a client requests a password change?

I'm encountering issues after this update—any help would be appreciated.

Hi @Nermin,

1.  This isn't an error we've had reported before. Are you perhaps using a custom Theme?

If so, does the issue persist if you switch to the stock Twenty One theme?

2. In WHMCS v8.x, in line with best-practice security design, staff cannot view a User's current password.

If you need to reset a client's password for them you may do so from the Users tab by following these steps: https://docs.whmcs.com/8-13/clients/client-management-tutorials/set-a-user-password-manually/

For more information, see: https://docs.whmcs.com/8-13/clients/client-management-tutorials/reset-a-user-password/

Hello,
 

If so, does the issue persist if you switch to the stock Twenty One theme?
>> When I switched to the Twenty One theme, the errors disappeared and the login area worked properly. However, I’d like to continue using my NH theme, which I’ve been using for years without issues. Could you clarify what changed in the latest update that caused the error below?

Hi @Nermin,

Thanks for confirming. Please make sure you've applied any updates from the theme vendor for compatibility with v8.13 and the latest PHP versions.
