 * Hi Community,
 * I am running my wordpresswebsite with the setup below.
 * MAC BOOK
    MAMP 4.1.1 PHP 7.1.1
 * WordPress 4.9.2
    Child Ken Version: 3.4.1 Ken Version: 4.1 WPBakery Page Builder(
   Modified Version) 5.4.5 Wordfence Version 7.0.1
 * Since today all my sites suddenly show a fatal error message below the page content.(
   see screenshot: [http://tinyimg.io/i/VjaZdrg.jpg](http://tinyimg.io/i/VjaZdrg.jpg))
 * The error message says:
 * Fatal error: Uncaught wfWAFStorageFileException: Unable to verify temporary file
   contents for atomic writing. in /home/www/mywebsite/wp-content/plugins/wordfence/
   vendor/wordfence/wf-waf/src/lib/storage/file.php:46 Stack trace: #0 /home/www/
   mywebsite/wp-content/plugins/wordfence/vendor/wordfence/wf-waf/src/lib/storage/
   file.php(567): wfWAFStorageFile::atomicFilePutContents(‘/home/www/mywebsite…’,‘
   <?php exit(‘Acc…’) #1 [internal function]: wfWAFStorageFile->saveConfig() #2 {
   main} thrown in /home/www/mywebsite/wp-content/plugins/wordfence/vendor/wordfence/
   wf-waf/src/lib/storage/file.php on line 46
 * I have no Idea what caused this issue but it seems wordfence related.
    Please
   let me know if you are familiar with this problem and know what I could do to
   fix it.
 * I would loose about 3 days work If I would need to revert to my latest backup
   so I am hesitant to do so.
 * Also please tell me if you need any additional information to be able to assess
   the situation.
 * Thank you in advance for your time,
    best regards, Max

 * Hi [@maxident](https://wordpress.org/support/users/maxident/),
 * [This topic](https://wordpress.org/support/topic/error-unable-to-verify-temporary-file-contents-for-atomic-writing/)
   discusses the same issue; the solution suggested by my colleague seems to have
   fixed the problem.

 * Thats it, the solution in my case was also running out of space on my webhost
   without realising. Once I cleared some space all worked again. Thank you
