Operation not permitted in storage/file.php

Hi @alsur,

This does, from the error messages, look like either a permissions or file-locking issue on your site. Do you see any connectivity or permissions fail/error messages in your Wordfence > Tools > Diagnostics page? A specific area to check would be “Filesystem” near the top, but worth having a quick glance down the page just in case.

It’s also worth checking that permissions on your WordPress site’s directories are 755, and that the process owner is www-data if appropriate for your setup. If you’ve recently upgraded to PHP8, it could be worth seeing if this persists when rolling back to PHP7.4.

Once you’ve checked those, in your FTP or hosting file manager, navigate to your wp-content/wflogs folder. You should be able to delete the wflogs folder or its contents entirely and Wordfence should try to repopulate it within 30 minutes. If you have persistent problems with file-writing permissions, you can bypass Wordfence’s requirements entirely by setting logs to use the MySQLi storage engine: https://www.wordfence.com/help/firewall/mysqli-storage-engine/

Thanks,

Peter.

Hi, thanks for prompt feedback.
Filesystem diagnostics all look ok.
I deleted the wflogs directory and it was recreated, so I am uncertain if I should ignore the warning completely.

Thanks.

Hi @alsur,

As warnings are non-fatal you could certainly try to continue running things as they are and see if you notice any issues going forward. If there appear to be no errors or problems in the running of Wordfence or the rest of your site then it may have been temporary.

chmod will only work without sudo if the owner of the file is the same as the one running the command, so it could be an issue where the files are owned by root (for example) but Wordfence and other WordPress plugins will be trying to perform file operations as www-root. It could be worth reviewing this in your hosting file browser or via FTP and see whether you can change the owner.

Thanks,

Peter.
