"Security Issues Detected" error

For some time now my dashboard (v4.5.0.1 and several earlier versions) has been reporting security issues on some sites. However, when I click the button to see what the issues are for a specific domain, I’m met with a page of potential issues with a bunch of spinning circles on the left that never stop.

And I get a “Your Site is Experiencing a Technical Issue” email from WordPress on the dashboard site that includes the following error details:

An error of type E_ERROR was caused in line 598 of the file /sites/[my dashboard domain]/files/wp-content/plugins/mainwp-wordfence-extension/class/mainwp-wordfence-config.class.php.

It appears that I can fix the issues by clicking the wrench icon. I tried it on one site, but I am not willing to “fix” more of them without being able to see what the issues are.

I keep thinking this is a pretty obvious problem that should get fixed in an update, but so far it never does.

Any ideas?

Hi @johnm

Can you please post some screenshots (where do you get the report of a security issue, where do you click the wrench icon to fix the issue, etc…) of the issue so we have a better understanding of the context?

And 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.
