My fix was to update the permissions on all the files in the wp-content/wflogs directory to ensure that Apache has read/write access to them. Doing this fixed the white screen issue. * Thread Starter [rabmcnab](https://wordpress.org/support/users/rabmcnab/) * (@rabmcnab) * [9 years, 11 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-7505392) * [@braican](https://wordpress.org/support/users/braican/) * Lol, I realise that I didn’t read the original stack properly and created the writable wflogs directory in the wrong place. D’oh. * As it happens I didn’t need to have this file writable by apache, I set permissions and group to the chrooted user/group that the site runs under. Initially had to make it writable, after it had created the php files (php files in a logging directory in wp-content??) I could set it back to 755 and all seems fine. * [WFSupport](https://wordpress.org/support/users/wfsupport/) * (@wfsupport) * [9 years, 11 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-7505393) * We’re working on a fix now that should be released later today. * The white screen or wfWAFStorageFileException error means that wflogs or wflogs/ config.php isn’t readable or doesn’t exist. The site can be fixed by adjusting file permissions so the web server can read/write those files, if possible, or by adding these two lines to the theme’s functions.php: * _remove\_action(‘wp\_enqueue\_scripts’, ‘wordfence::enqueueAJAXWatcher’); remove\ _action(‘admin\_enqueue\_scripts’, ‘wordfence::enqueueAJAXWatcher’); The two lines can be removed after the new update is released. * Thread Starter [rabmcnab](https://wordpress.org/support/users/rabmcnab/) * (@rabmcnab) * [9 years, 11 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-7505397) * OK, thanks [@wfsupport](https://wordpress.org/support/users/wfsupport/) * Good luck today, might be quite a busy one for you I think 😉 * [jesseamber](https://wordpress.org/support/users/jesseamber/) * (@jesseamber) * [9 years, 11 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-7505408) * [oops, ignore me] * [Senuke](https://wordpress.org/support/users/cavor/) * (@cavor) * [9 years, 11 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-7505449) * Thank you for quick patch, works perfectly now 🙂 * [tenfef](https://wordpress.org/support/users/tenfef/) * (@tenfef) * [9 years, 3 months ago](https://wordpress.org/support/topic/wfwafstoragefileexception/#post-8746122) * This error was happening to me when the host ran out of disk and couldn’t write a temporary file.
