Where can I change log permissions so other programs can read apaches web logs?

Click on the “Tweak Settings” link under “Server Setup”. Within the “Stats and Logs” section is a text box with the heading:

“Chmod value for raw apache log files (0640 is the default):”

Change the value to suit your needs and apply the changes by clicking on the “Save” button at the bottom of the page.

Most programs only need read permissions on the log files so setting this to 0644 should suffice.

How to enable iconv on CPanel server?

The iconv API is the standard programming interface for converting character strings from one character encoding to another in Unix-like operating systems. Initially appearing on the HP-UX operating system, it was standardized within XPG4 and is part of the Single UNIX Specification (SUS).

All recent Linux distributions contain a free implementation of iconv() as part of the GNU C Library which is the C library for current Linux systems. To use it, the GNU glibc locales need to be installed, which are provided as a separate package (usually named glibc-locale) normally installed by default.
