Warning: Attempt to assign property ‘external’ of non-object

Hello @dccorp and thanks for reaching out to us!

Where are you seeing this error? Is it the debug log or the scan log? Are you noticing anything on your site that is not working properly? Anything change recently to prompt this?

Thanks!

Hi, thanks for answer

It’s in the scan log, the last line.

No strange behavior on site, everything seems to be ok.

It’s a new wordfence installation on a small site with litespeed and oxygen builder. The error appeared from the first scan.

I’m monitoring several sites via wordfence central, but this is the only one with litespeed and oxygen builder.

.htaccess is configured as requested for litespeed.

Can you run another scan and copy the last 20 lines of so from the log and paste them here for me to review?

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.

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.

Thanks!

Thank you,

Thanks for sending that @dccorp

I don’t see anything on your diagnostic that would cause that.

If you check your PHP error logs are there any other Notices, Warnings, or errors referencing plugins or the theme?

Assuming there aren’t any Fatal errors, Notices, and Warnings, this shouldn’t affect your site functionality as your scans are still completing.

Let me know what you find!

Thanks!
