Undefined array and property warnings in class-mainwp-cron-jobs-auto-updates.php

David_H · October 19, 2024, 10:30am

The following PHP Warnings are being generated every 5 minutes in my MainWP:

[19-Oct-2024 08:05:17 UTC] PHP Warning: Undefined array key “new” in /home/myuseraccount/public_html/mymainwp/wp-content/plugins/mainwp/class/class-mainwp-cron-jobs-auto-updates.php on line 284

Taking a look at that file, code lines 283 through 287 are this:

if ( isset( $information[‘sync’] ) && ! empty( $information[‘sync’] ) ) {
MainWP_Sync::sync_information_array( $website, $information[‘sync’] );
}
} catch ( \Exception $e ) {
// error.

Has anyone else encountered this? Is anyone from MainWP familiar with and can possibly provide a solution suggestion?

Thank you for any feedback.

Hey @David_H, I’m not seeing other tickets on this, which leads me to believe it may be something server-side and thank you for sending over the server config code with your issue

Let’s look into the following:

TL;DR:

Increase the cURL timeout from 60 seconds to 300 seconds.
Reduce the number of simultaneous sync requests (try 4 or 2) to lower the server load.
Temporarily disable Solid Security Pro to rule out conflicts.

Here’s why: based on your server setup and active plugins, a few things that could contribute to the issue stand out.

cURL Timeout (60 seconds - Warning)

Your cURL timeout is currently set at 60 seconds, but your MainWP Dashboard should be at 300 seconds. If external requests, like pulling update data for connected sites, take longer than 60 seconds, this could lead to incomplete or corrupted data during the sync process, which might be causing those warnings about undefined array keys or properties.

Fix:
Increase the cURL timeout to 300 seconds. This can usually be done in your server’s php.ini file or by asking your hosting provider to make the change.

Server Performance (232 Connected Sites)

You have 232 connected sites, and your dashboard is set to sync 8 sites at a time. While this is generally fine, if your server is under heavy load, those sync requests might timeout or fail, which can cause missing data during auto-updates.

Fix:
Consider reducing the number of simultaneous sync requests to ease the load. Try lowering it from 8 to 4 or even 2 and see if that improves performance.

Go to the Menu on the top right. Click the (…) to expand the menu > Settings > Advanced Settings.
Set “Maximum Simultaneous Sync Requests” to 4 or 2.

3. Solid Security Pro

The Solid Security Pro plugin could be interfering with certain processes. Security plugins sometimes block or modify requests related to cron jobs, automatic updates, or file permissions. It’s worth temporarily disabling this plugin to see if the PHP warnings stop.

Fix:

Temporarily disable Solid Security Pro and see if the issue persists.
Check the plugin’s settings to see if anything might be blocking background processes, like file permissions or API requests.

One of those should help with the issue, but if it doesn’t, please let us know, and technical support can follow up on Monday.

@dennis - thank you very much for the detailed response and advice. I made all of the adjustments that you suggested, and I thought I had the issue narrowed-down, but it looks like a couple days of testing may be needed on my part as time allows. I’ll be sure to post back here with any results and discoveries.

Hello, I have had the same problem as described above for about 3 weeks. My cronjob runs every morning at 5am. Every morning at 5 a.m. I receive an e-mail with the error message (this is my setting in Plesk).

I would also be grateful for a solution. Best regards, Sven

Hi @svehei and @David_H

I am unable to reproduce this on my test Dashboards.

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

And please refer to this Managers thread by its URL in the ticket.
