Title: Scan failed Last modified: July 13, 2017 --- # Scan failed * [giuliferi90](https://wordpress.org/support/users/giuliferi90/) * (@giuliferi90) * [8 years, 11 months ago](https://wordpress.org/support/topic/scan-failed-5/) * Hello ! Trying to scan I get this error: “The current scan looks like it has failed, and its last status update was 16 mins ago, and you can continue to wait for it to resume or cancel and restart the scan. Run scans reliably. Click here for the steps you can try. ” I clicked on to find the solution and went to the“ options” page of the scan and in the “Time limit that a scan can run in seconds” page I wrote before 15 then 20 as a board. I tried to rescan the scan, but I get it “Scan interrupted. You have 1 new issue to fix. See below.” So I went to the tools page, I clicked on the diagnostics and at the end of the page I clicked on “Click to view your system’s configuration in a new window”. Here I have to find “max_execution_time” is changing “Maximum Run Time for Each Scan Phase” but how do you do it?

But today after the update of WordPress the problem has reappeared and the scan fails and i am the same error 3 weeks ago, I tried to disable and reactivate then i try going on: – options – “How much memory should Wordfence request when scanning” and here I increased to 300 I tried again but did not finish Sorry my ignorance but what does the debug mode mean? And how does it work? * Thanks so much - This reply was modified 8 years, 10 months ago by [giuliferi90](https://wordpress.org/support/users/giuliferi90/). * [wfalaa](https://wordpress.org/support/users/wfalaa/) * (@wfalaa) * [8 years, 10 months ago](https://wordpress.org/support/topic/scan-failed-5/#post-9379017) * Hi, Debug mode should reveal more information in the scan activity log about what the scan is doing step by step which should help us understanding why it hangs. * If there is any running scan at the moment, please click on “Click to kill the current scan” then make sure “[debug mode](https://docs.wordfence.com/en/Wordfence_diagnostics#Enable_debugging_mode_.28increases_database_load.29)” is turned on and run a new scan, when it hangs again, click on “Email activity log” and send the log to “alaa [at] wordfence [dot] com”. * Thanks. * Thread Starter [giuliferi90](https://wordpress.org/support/users/giuliferi90/) * (@giuliferi90) * [8 years, 10 months ago](https://wordpress.org/support/topic/scan-failed-5/#post-9380533) * How do I activate debug mode?

I enabled debug mode and when I stopped I click on “Email activity log” and sent to [alaa@wordfence.com](https://wordpress.org/support/topic/scan-failed-5/alaa@wordfence.com?output_format=md). it’s right ? Now what should I do ?

If so, are you sure the scan is hanging at this stage? could you please refresh the scan page and kill the scan then run a new one? * Thanks. * Thread Starter [giuliferi90](https://wordpress.org/support/users/giuliferi90/) * (@giuliferi90) * [8 years, 9 months ago](https://wordpress.org/support/topic/scan-failed-5/#post-9431735) * Hi, the site is that. I tried to update the page, kill the scan and run another, but I always get the same message “Scan Failed: The current scan looks like it has failed. In case it resumes or cancel and restarts the scan. Some sites may need adjustments to run scans reliably. ” what should I do ?

So I sent the report by email to [alaa@wordfence.com](https://wordpress.org/support/topic/scan-failed-5/alaa@wordfence.com?output_format=md), with the name giuliferi90.

The scan is complete! I did not control the browser console, but did not help because the scan was completed, right? Thanks so much! You have been very kind! * [wfalaa](https://wordpress.org/support/users/wfalaa/) * (@wfalaa) * [8 years, 9 months ago](https://wordpress.org/support/topic/scan-failed-5/#post-9455923) * I’m glad you managed to get it working! there is no need now to check the browser console. * Thanks.
