Can’t scan since update

Hi @wpelvis,

Have you tried applying the solutions outlined in this article?

If the issue persists, please enable the debugging mode and post here the last 20 lines or so of the activity log after starting a new scan.

This is still a problem for me.

Here is last bit of the log

Hi @wpelvis,

Apologies for the delayed response.

Although it isn’t directly related to Wordfence, the error displayed in the log

ob_end_flush() [ref.outcontrol]: failed to delete buffer zlib output compression (8) File: /home/savethemale/public_html/wp-includes/functions.php Line: 3720

points to a part of the WordPress code that should apply when the site is using PHP version 5.2.

In case you’re running that specific version of PHP, this would also explain the difficulties Wordfence has to perform the scan in a timely manner. (see here Wordfence requirements)

If you’re using a more recent version, please note that the latest Wordfence update (6.3.10) includes an improvement of the overall memory usage and peak memory usage for the scanner, which appears to be high in your case

Wordfence used 120.19MB of memory for scan. Server peak memory usage was: 254.83MB

Please upgrade PHP and/or Wordfence and let me know if the scan is able to run to completion.
