Fatal error on line **534**

Hello, I have a fatal error on most of my sites, I can’t connect because of this:
Warning : Attempt to read property “expiry_date” on null in
XXX/XXX/wp-content/plugins/mainwp-domain-monitor-extension/class/class-mainwp-domain-monitor-admin.php** on line 534

What am I supposed to do? Thanks,


Hi @seguelac

Welcome to the MainWP Community!


I assume that you are seeing this Warning on your MainWP Dashboard site?

Are you seeing a different Fatal Error on your child sites? If so, can you give us more information about that?

Finally, can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → 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.

Also, please include the system report for the Child Site in question by navigating to MainWP Child > System Information and clicking the Blue button.
