User's can't modify password

[Runrev]

We're experiencing a rather strange issue whereby user's can't use cPanel's Change Password feature, but passwords can be successfully reset using WHM.

The Change Password screen loadsand appears to submit, but the second page is blank and clicking the "show raw password change" link producing only a black box.

Errors are generated in /usr/local/cpanel/logs/error_log:

We're running cPanel version 11.38.2 (build 6), in fact we're running several servers with this, but only one of them has this problem.

Does anyone have any ideas how we might fix it?

Hello

It's likely the "devpts" filesystem is missing from your /etc/fstab file. Check that with a command such as:

grep devpts /etc/fstab

You may want to consult with a qualified system administrator or your data center to ensure it's properly configured.

Thank you.
