Hi @dlmweb!
Is this actually preventing the scan from completing or are you just seeing the errors in the scan log, but the scan completes?
I think it looks like the issue could be that you have a plugin installed that doesn’t have a plugin version defined properly. But I wouldn’t have expected this to stop your scan.

I believe the scan does complete. Below is a snippet of the log which shows a Quick Scan Complete and a Scan Complete:

I’ve looked at the plugins and all are ones that I use on dozens of other client sites without issue…. Gravity Forms, TablePress, Genesis plugins, etc. so I wouldn’t expect those to throw an error, but perhaps tonight I can deactivate them all and try the scan again.
Given that the scan completes, can I safely ignore the errors?
Thank you.
Hi again @dlmweb,
I checked the code corresponding to this warning message and it looks like it’s part of the test that checks for vulnerable plugins and the “version” data is coming from the ww.wp.xz.cn repository there. That would mean you have a plugin with a particular slug and when we try to fetch information about that plugin from ww.wp.xz.cn we receive a reply that doesn’t contain a version for some reason.
I do think disabling plugins is the easiest way to find out which one is causing it. I’d disable all of them first, if the error is then gone, enable half of them. If the error is still gone, you now know it’s coming from one in the other half (that you haven’t activated yet).
If you figure out which one it is feel free to share if you want as it may help others who stumble on this thread in the future.
But yes, you can also choose to ignore it if you prefer. It basically means we’re failing to check the status of one plugin because we’re not able to get a version for it.
Hi @dlmweb,
We haven’t heard back from you in a while. 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!
