Its possible to enable the entry log, but not log entries by certain staff/accounts. For example, a site developer or owner might not want his/her log entries to appear.
For accounts, you can enable / disable the entry log on the relevant account edit screen. To disable admin staff, open the 'control/options.php' file in a text editor and look for the following:
define('ENTRY_LOG_SKIP_USERS', '');
Enter email addresses separated with a comma. This is not case sensitive. So, for example, to disable logging of the following:
johndoe@example.com
ayumihamasaki@example.com:
You would enter:
define('ENTRY_LOG_SKIP_USERS', 'johndoe@example.com,ayumihamasaki@example.com');
To disable logging for the global admin user as set in the 'admin/control/access.php' file use the following variable:
GLOBAL_NO
define('ENTRY_LOG_SKIP_USERS', 'GLOBAL_NO,johndoe@example.com,ayumihamasaki@example.com');
