When trying to view log files of IIS based domain the following error is displayed:

ERROR: PleskFatalException

Unable to open log file: gzopen failed: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for 'UTC/0.0/no DST' instead

There are following errors can be found in /usr/local/psa/admin/logs/panel.log:

PA cannot open the file as IIS locks the log to write in it.

The corresponding software issue #PPA-3352 was submitted. The fix is planned to be included in one of the future product updates.


View the log file through the file manager.
