Error in "Tweak Settings" after saving settings

[nyol]

Hi
I have the latest version of cpanel installed on a VPS, all done cleanly.
However, any changes I make in "Tweak Settings" generates an error when I click in button save.

[a fatal error or timeout occurred while processing this directive]

This message shows a log

Someone can tell me why this is happening? I'd like to fix that.

Thanks guys

Hi guys

No help yet, my hopes are already depleted.

I really can not find an answer on google.

If someone has gone through this please share the solution.

thank you

Hi nyol, please feel free to open a ticket to cPanel Technical Support about this:

I've noticed this issue on a number of cPanel 11.36 servers recently. I never saw it happen in 11.34.

From the error message it seems cPanel & WHM is unable to obtain a lock on the /var/cpanel/cpanel.config file. This is not something we've encountered in our testing. In order to resolve, or diagnose, the issue we need access to a machine that encounters this symptom. Please open a support ticket with us next time it occurs.
