Title: Scan hangup Last modified: July 3, 2020 --- # Scan hangup * Resolved [Indent](https://wordpress.org/support/users/indent/) * (@indent) * [5 years, 11 months ago](https://wordpress.org/support/topic/scan-hangup/) * I’ve been using Wordfence (free version) couple of months with no problems. I don’t understand why it suddenly says “The current scan looks like it has failed.” I’ve added `define('WORDFENCE_SCAN_FAILURE_THRESHOLD', 600);` in wp-config.php, also edited the Scan Options & Scheduling > Performance Options > Maximum execution time for each scan stage to 20. The scan always stops at 5554 analyzed files with notification of “Scan Failed”. Any suggestions?

Content > wflogs folder is also created, no changes in .htaccess though. - This reply was modified 5 years, 11 months ago by [Indent](https://wordpress.org/support/users/indent/). - This reply was modified 5 years, 11 months ago by [Indent](https://wordpress.org/support/users/indent/). - This reply was modified 5 years, 11 months ago by [Indent](https://wordpress.org/support/users/indent/). * [WFSupport](https://wordpress.org/support/users/wfsupport/) * (@wfsupport) * [5 years, 10 months ago](https://wordpress.org/support/topic/scan-hangup/#post-13180062) * Thanks for letting us know. * Can you try these steps again so we can see the scan log entries? * * Kill the existing scan if it is still running (The “Start New Scan” button turns in to a “Stop” button while the scan is running) * Go to your Scan > Scan Options and Scheduling page and locate the “Performance Options” * Set “Maximum execution time for each scan stage” to 20 on the options page * Click to “Save Changes” * Go to the Tools > Diagnostics page * In the “Debugging Options” section check the circle “Enable debugging mode” * Click to “Save Changes”. * Start a new scan * Copy the last 20 lines from the Log (click the “Show Log” link) or so of the activity log and paste them here * Tim * Thread Starter [Indent](https://wordpress.org/support/users/indent/) * (@indent) * [5 years, 10 months ago](https://wordpress.org/support/topic/scan-hangup/#post-13180519) * I’m not sure how that’s possible. * > Can you try a complete reinstall?
