Title: Empty log files Last modified: March 7, 2018 --- # Empty log files * [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/) * Weekly backups are completing without apparent issues, and log files are being created and emailed to us, but there is nothing in them. This is one of many sites I monitor on the same servers with the same BackWPup settings, and the log files are fine on the others. What could be causing this? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fempty-log-files%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/empty-log-files/page/2/?output_format=md) [→](https://wordpress.org/support/topic/empty-log-files/page/2/?output_format=md) * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10049640) * Hi [@syzygist](https://wordpress.org/support/users/syzygist/) Can you see log files in BackWPUp **Log file folder** section? ( BackWPUp -> Settings -> Log file folder ) I means, using a file manager plugin or FTP access to see files inside **Log file folder** path * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10050129) * Yes. I downloaded the most recent one and checked it. It’s the same as the logs I’m receiving by email, headers only, i.e., all of the lines beginning with [ INFO], but nothing below that. * Log level is showing as Normal in the header and Normal (translated) – which I assume means human readable – in the settings. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10052242) * [@syzygist](https://wordpress.org/support/users/syzygist/) weird, please go to BackWPUp -> Settings -> Logs -> Logging Level -> Debug(not translated ),re- run the job and check the latest log file again. Can you see the log? * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10054405) * Yes, it looks like a full log when set to Debug (not translated). * So after I did this, I set it back to Normal (translated) and ran it again – empty log file again. I tried viewing the log while the job was running, and it looked like nothing was writing to it. * Then I set the logging to Normal (not translated) and backed up again. That gave the same result as Normal (translated) – [INFO] header lines only, no log content. * I thought I might as well round out the experiment by running it with a Debug( translated) log. This produced a log that looked a lot like the Debug (not translated) log, so I switched the setting back to Debug (not translated) in case I had chosen the wrong debug setting the first time, and ran it one last time. This produced the same log I got the first time, so I guess there is no difference between Debug (translated) and Debug (not translated)? * Don’t know whether this helps, but we reviewed emailed log files and determined that the last normal log was on 9/27/17. On the next backup, 10/4/17, we saw the first empty log. I note that there was an update from vs. 3.4.1 to 3.4.2 during that interval. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10057231) * Hi [@syzygist](https://wordpress.org/support/users/syzygist/) So you can see the full log after set BWP logging level to debug? * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10057575) * Yes. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10059378) * [@syzygist](https://wordpress.org/support/users/syzygist/) Could you check your server log or give it in here? Is there any error in your server log? * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 3 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10061012) * No, no errors in the server log for the past week. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10064419) * [@syzygist](https://wordpress.org/support/users/syzygist/) So I think maybe your wp-config has disabled debug mode, could you please add these line to the wp-config.php file to see if WordPress throws any error? Edit your `wp-config. php`, before `/* That's all, stop editing! Happy blogging. */` Add this line ` define( 'WP_DEBUG_LOG', true );` After that try to run the job again then go to your wp-content folder to see if there are a file named debug.log. Do you see any error in **debug.log** ? * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10067312) * I added `define( 'WP_DEBUG_LOG', true );` to wp-config and ran the backup job, but there was no debug.log in wp-content. Then I tried changing `define('WP_DEBUG', false);` to `define('WP_DEBUG', true);` and ran the job again, but still no debug log. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10077502) * Hi [@syzygist](https://wordpress.org/support/users/syzygist/) it’s really weird, never get this problem before. Could you please try to uninstall BackWPUp and after that, reinstall it again to see if this problem got fixed? Thanks! If not, I really don’t know what happens 🙁 * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10078462) * If I uninstall, will I lose my backup files, log files, or jobs I have already set up? * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10081761) * [@syzygist](https://wordpress.org/support/users/syzygist/) You will lose your jobs settings, all backup files and log files will not be intact 🙂 * Thread Starter [syzygist](https://wordpress.org/support/users/syzygist/) * (@syzygist) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10082511) * So I will lose the backups and logs as well? * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years, 2 months ago](https://wordpress.org/support/topic/empty-log-files/#post-10082579) * [@syzygist](https://wordpress.org/support/users/syzygist/) of course, NOOOO 🙂 you won’t lost the backups and logs 🙂 Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/empty-log-files/page/2/?output_format=md) [→](https://wordpress.org/support/topic/empty-log-files/page/2/?output_format=md) The topic ‘Empty log files’ is closed to new replies. * ![](https://ps.w.org/backwpup/assets/icon-256x256.png?rev=3236141) * [BackWPup – WordPress Backup & Restore Plugin](https://wordpress.org/plugins/backwpup/) * [Support Threads](https://wordpress.org/support/plugin/backwpup/) * [Active Topics](https://wordpress.org/support/plugin/backwpup/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/backwpup/unresolved/) * [Reviews](https://wordpress.org/support/plugin/backwpup/reviews/) ## Tags * [empty](https://wordpress.org/support/topic-tag/empty/) * [files](https://wordpress.org/support/topic-tag/files/) * [log](https://wordpress.org/support/topic-tag/log/) * 18 replies * 2 participants * Last reply from: [syzygist](https://wordpress.org/support/users/syzygist/) * Last activity: [8 years, 1 month ago](https://wordpress.org/support/topic/empty-log-files/page/2/#post-10195739) * Status: not resolved
