Error Log featire not working as expected
The "Error Log" icon in cpanel fails to parse the /usr/local/apache/logs/error_log file correctly - period!
Ticket 4201923 shows the issue in full, but briefly, cPanel skips most of the error_log file, and unless something from the particular cpanel account appears in the last few lines of the log, then it doesn't appear. This is utterly useless on a busy server. Even a relatively small error_log file of less than 100Mb is not parsed correctly for a user's errors.
