These are situations where a non-fatal error may be expected, but can safely be ignored. * However, your custom error handler does not appear to support this. Your error handler should check that `error_reporting() === 0`, and abort if so (See [http://php.net/set_error_handler ](http://php.net/set_error_handler) for more details). * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10622056) * This is to say… in your custom handler, you are logging events whose type PHP is advising you are set to be ignored. * In [http://php.net/set_error_handler](http://php.net/set_error_handler), look at the paragraph beginning ‘It is important to remember that’; in particular the info about the @ operator. * Thread Starter [egycode](https://wordpress.org/support/users/egycode/) * (@egycode) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10622484) * Thank you both, [@dnutbourne](https://wordpress.org/support/users/dnutbourne/) and [@davidanderson](https://wordpress.org/support/users/davidanderson/) * I commented the case switch statement code in the function to log all error types! My bad! * But I think this error is a different situation, though * [23-Aug-2018 02:24:42 UTC] PHP Notice: Undefined index: others in /wp-content/ plugins/updraftplus/backup.php on line 664 * Thread Starter [egycode](https://wordpress.org/support/users/egycode/) * (@egycode) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10622533) * By investigating the last error, i found it related to the prune_retained_backups function and it seem to occur every day when the backup is being created and uploaded to google drive, the index others may be associated with the folder others and it is triggered while deleting the retained backup from the remote server on gooole drive! * I reviewed the backup files on my google drive account and i found that backups created on 22nd of this month didn’t prune, I set the retain version to only 1, so from my understanding it should retain the backup created on 23rd and delete the backup created on 22nd? or I’m wrong! * Plugin Contributor [DNutbourne](https://wordpress.org/support/users/dnutbourne/) * (@dnutbourne) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10632962) * Hi, * Apologies for the delay. * Please could you send us a copy of the latest backup log where this issue occurs? The contents will be too long to post here directly, but you can use an online service such as Pastebin, and post the link here. * Best Wishes, David N * Thread Starter [egycode](https://wordpress.org/support/users/egycode/) * (@egycode) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10634171) * Sorry, the log file has been deleted and this error didn’t occur in the last days! maybe it happen only if you try to create a specific backup like others folder after an automatic backup already created, the plugin will delete the most recent same backup part (others folder) from the last full backup on remote storage! Is this implemented in your code? * Have a nice day! * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [8 years ago](https://wordpress.org/support/topic/fclose-and-unlink-errors/#post-10638197) * > [23-Aug-2018 02:24:42 UTC] PHP Notice: Undefined index: others in /wp-content/ > plugins/updraftplus/backup.php on line 664 * There is indeed a gremlin there.
