Vulnerability Checker - "Schedule automatic checks" and "Check sites when syncing" not working

I installed the Vulnerability Checker extension over a month ago and it checks my sites fine when I run it manually (using MainWP NVD API).

The one thing I notice is that the “Schedule automatic checks” I had set to daily (I have also tried weekly) never seems to work. “Last Run” always says Never and “Next Run” says Today under Settings.

“Check sites when syncing” is enabled as well but I don’t think it does anything as well since in the Vulnerability Checker Overview list “Last check date” column for any of my sites is always the date I last time did a manual check.

I have other scheduled tasks running like the Pro Reports so I am not sure why the Vulnerability Checker schedule doesn’t seem to work.

Anyone have any ideas on how to fix it?

Hi Tom,

Can 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.

Hmm never knew about the service status page, nice. I see that my WP memory limit is reported a little low but I will not change anything until you take a look. The only other thing that is not passed is the cURL timeout is a little low as well but neither should prevent a schedule from running especially syncing more heavier tasks like scheduled synching child sites runs without problems.

Here is a bit more info on the issue.

So I looked at MainWP Cron Schedules and I notice that the “Last Run” date is missing for
mainwp_cron_vulner_recheck
mainwp_maintenance_cron_scheduled_continue
mainwp_maintenance_cron_scheduled_start

Now I believe the maintenance cron is running because in the pro reports it does display maintenance information for each child site. I also manually ran mainwp_cron_vulner_recheck using the WP Control plugin and the dates for the “Last check date” for each child site did not change.

Here is the info from the Vulnerability Checker Overview

Hi Tom,

Can you please try to update the WP Memory Limit to at least 128M and see if that helps?

It’s weird it should already be at 256 (which is what I set all my sites at when I create them). I just confirmed and I have PHP memory set at 256MB. My backup plugin on the same site also states in its website info page that the memory_limit is at 256.

I even added in wp-config.php

define (‘WP_MEMORY_LIMIT’, ‘256M’);

and rebooted the server but for some reason MainWP thinks the WordPress Memory Limit is 40M

Could there be a bug on the MainWP Server Info page?

Can you please check your code? Now it looks like you are using curly quotes. They must be straight. Like this:

define( 'WP_MEMORY_LIMIT', '256M' );

Oops… okay that works and now the WP Memory Limit has been set.

Still 12 hours later and the vulnerability checker has not automatically run.

Should those cron jobs listed by the extension that I have listed above have last run dates (some do and some don’t as I listed above).

If I trigger the cron job “mainwp_cron_vulner_recheck” should that check the schedule and trigger anything over due? (I just tried it and the last run date did not change). Currently that cron job is scheduled hourly.

Hi Tom,

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

Okay, I just opened a ticket.
