Unable to Complete Scan

Hey @geweb,

Can you do the following so I can get the information I need to help you?

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

Please let me know.

Thanks,

Gerroald

Hey @geweb,

We haven’t heard back from you in a while, so I’ve gone ahead and marked this thread as resolved.

Please feel free to open another thread if you’re still having issues with Wordfence.

Thanks,

Gerroald

I apologize for not getting back to you sooner. I was finally able to follow the steps you sent today. The scan failed again because it timed out. It reached the 6 hour time limit.

Please let me know your thoughts on this.
Thank you!

Thanks for sending that. It looks like 6 hours wasn’t enough time to finish the scan. Try upping it to 8 hours (28800) and see if it completes then.

Is there anything different about your site in particular? Are there any symlinks in the public_html folder (eg: if you are creating a symbolic link for /images which points to /wp-content/uploads or similar)? Do you have a lot of folders inside the WordPress installation directory like other WordPress sites or other large folders?

I am trying to run the scan again now. Hopefully with 8 hours it will finish. I don’t think there is anything particularly different about our site. We are an engineering/building inspection firm. We have a lot of project photos, but I have optimized most, if not all of them, for website use. Our plugins are all updated and I removed all unnecessary themes. There are no other WordPress sites running through this one and no additional WordPress installations. Would it help to know what themes and plugins we have installed?

Thank you for your assistance!

I tried the scan again. The scan terminated after 7 or so hours. It once again said that it terminated due to a possible infinite loop.
