Vulnerability Scanner Undefined Error

I installed and attempted to use the Vulnerability Scanner but no matter how I run it all I get for each site is an UNDEFINED ERROR PLEASE TRY AGAIN.

Any ideas?

Following as I have the same issue here.

Snap! Following, same issue.

Strange, we’ve had this in public beta for around 30 days with no reports of this happening.

Can each of you please post the community system report from your MainWP Dashboard for review?

The report is located in your Dashboard under Status → Server, on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:

Pressing the button auto-copies the report to your clipboard then just paste it in a reply here.

I found this but it was actually in the leftmost menu on the bottom. Here’s the data. And thanks!

I couldn’t duplicate this issue.

Would you mind opening a private Help Desk ticket so we can collect some additional information & investigate further?

Will this issue be updated with info from the private ticket? I have the same issue

As soon as we find what is going on, we will post the solution here.

Support suggested that I remove ALL the extensions and then reinstall/activate – and that worked!

Same problem.
No errors in the logs.

However I fixed a similar problem with the Sucuri extension (same message, undefined error),
It was an obsolete hook (mainwp-sucuriscan-sites => mainwp_sucuriscan_sites).

Maybe there is also an obsolete hook in VulnChecker, that was’nt properly flagged as deprecated ?
A lot of hooks names were modified recently, with “-” replaced by “_”

mainwp-vulner.js is expecting ‘error’ or ‘ok’ in the ajax response, but these params are not in the php (do_vulner_result_recheck)

So js/php seems out of sync. Maybe a permission problem while updating.

This did not work for me. I uninstalled all of the extensions, re-installed and activated only the Vulnerability Checker extension … same error as reported above. I’ll create a support ticket.

EDIT: I submitted a support ticket, but I don’t see it in the list of “My Support Tickets,” so I’m not sure if it worked.

+1 - We’re experiencing the same issue. Never used this extension before so installed from scratch and this is the error we get on every site when hitting the ‘Check all sites’ button.

same issue here, is there a fix for this?

We are still working on our investigation process as this is not effecting everyone the same way. Thank you for your patience.

As a follow up on this, support and @bogdan have yet to receive any tickets with a way to test and find the issue, we are not able to duplicate on our setups

Same issue here. looks like the last time it ran was 7/15/21. Not sure if that narrows it down at all.

Hi Roger,

We are still working on this. So far, we have inconclusive results. In all tickets that we have received the issue got resolved by itself or by reconnecting a site. But we couldn’t catch any actual bug in the code.

If you can, please try to reconnect one chid site and see if that allows you to run a scan for it. If it fails again, please open a helpdesk ticket.
