"Attempting to drop privileges to root" Error when click on cPanel icon in the "Account Information > List Accounts"

[NabiKAZ]

I have no problem logging into WHM and cPanel.

But when I click on the cPanel icon through the "Account Information > List Accounts" menu in WHM to enter the user panel. I get the following error:

Internal Server Error
500

Error ID 12335656f958b

I leave the log file and other information below.

Hello,

Kindly check .htaccess file permission.

@NabiKAZ - usually when this happens, there is some type of permission or ownership conflict on the account. Could you open a ticket with our team so we could investigate this directly?

Which .htaccess in which path?

This problem is not related to a specific account. There is this problem on all accounts and there is no access to the user's CPanel through WHM.

Well that's even more strange. Can you get that ticket opened so we can check it out?
