    I get this error during vulnerability scan. Any idea on a fix?

    Fatal error: Uncaught Error: Attempt to assign property “external” on array in /var/www/events/wordpress/wp-admin/includes/plugin-install.php:222 Stack trace: #0 /var/www/events/wordpress/wp-content/plugins/wordfence/lib/wfScanEng

    Hi @rtherrien, thanks for reaching out to us!

    Could we please see the full scan log output before this error occurs? You can do this by:

    • Going 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 or so from the Log (click the “Show Log” link) once the scan finishes and paste them in the post.

    Usually, this has something to do with a plugin or theme causing a conflict in the scanner. The log will usually produce a few errors to show what might be causing it.

    Thanks,

    Peter.

    Hi @rtherrien, thank-you for providing that.

    By the looks of things, this error has cropped up in the past when there is a large users database but I wouldn’t anticipate that with 11 users as reported in that log. There is also potential for Litespeed or another third party plugin to see the fatal error reported here.

    Can you please try a scan with all plugins disabled apart from Wordfence? Does the same thing occur? If not, try enabling plugins one-by-one until the fatal error reoccurs.

    If Wordfence still presents this error regardless of the status of other plugins, can you send a diagnostic report to wftest @ wordfence . com? You can find the link to do so at the top of the Wordfence Tools > Diagnostics page. Then click on “Send Report by Email”. Please add your forum username where indicated and respond here after you have sent it.

    Note: For the fastest response time, please make sure and add any information or questions directly to this topic and not the email address above unless asked.

    Thanks,

    Peter.
