Please make a screenshot with that error message.
Here is the link
I don’t know if that error message is coming from WP Cerber or AM360. But the AM360 login process worked before and now it does not, unless I deactivate WP Cerber. Or is there a setting somewhere?
Regarding this issue of logging in subscribers, I have an additional message showing up and it may be easy to address (I am looking into it). It says I am in maintenance mode and only admins can login.

Perhaps a separate issue, WP site health check has informed me: The scheduled event, cerber_bg_launcher, failed to run. I have WP-cron disabled in wpconfig and it instead is set to run every 45 minutes by the server.

I had no luck resolving the maintenance mode message on my alternative signon page but it might be a clue. As before, deactivating WP-cerber resolves these issues, and my subscribers can login.

Hi! First of all, it’s a conflict with another plugin. I think you just have installed too many plugins and this creates a mess. Also, the issue can be caused by a poorly designed membership plugin.
P.S. All messages on your screenshots are generated by other plugins, not Cerber.
Thank you for that feedback. My plugin stack has not changed in over a year, and in regards to membership plugin, it has not changed in several years and since I started also using WP-cerber. So this is a fairly recent development. When I deactivate WP-cerber, the problems are no longer present. It does seem rather obvious it is probably a conflict, but it came about apparently with recent changes to your plugin. I am in the process of setting up some PHP WP error logs and see what that says about the issue. I have not inquired yet with the membership plugin support.
Do you have any insights regarding the scheduled task cerber_bg_launcher, which according to site health check failed to run. Would this message result if I was using an external cron schedule on the server side?
I have reactivated your plugin and am trying to see what I can learn via the diagnostics. Although I do not know if this is related, do you have a recommended frequency with which to run the cron.
I may still have an issue with my cron scheduler:
Maintenance Tasks
Hourly task #1 has never been executed
Hourly task #2 has never been executed
Daily task has been executed 2 days ago and it took 0 seconds.
Hourly task #1 scheduled for July 15, 2019, 3:00 pm (in 9 mins)
Hourly task #2 scheduled for July 15, 2019, 3:10 pm (in 19 mins)
Daily task scheduled for July 15, 2019, 3:20 pm (in 29 mins)
Background tasks: 0
Note: the internal WordPress cron launcher is disabled on this site.
An external cron launcher has not been configured or does not work properly.
This is the response I got from AM360:
We use the standard WordPress authenticate filter to perform our validation/authentication based upon ActiveCampaign data any time a user logs in to WordPress.
See: https://codex.ww.wp.xz.cn/Plugin_API/Filter_Reference/authenticate
We call the filter as follows: add_filter( ‘authenticate’, [ $this, ‘authenticate’ ], 999, 3 );
The messages you are seeing are from ActiveMember360 from our own function hooked into authenticate.
Whatever changes WP Cerber have made recently this is obviously interfering with that process. If we understand you correctly this worked before their last update.
This is a process we have used in our plugins for ten years. There is nothing wrong in that respect with our process.
Given the above perhaps WP Cerber can determine what change they as made that would interfere with the authentication process.
Regarding the maintenance mode message in screenshot of alternate login above, per AM360 support:
ActiveMember360 only shows the maintenance mode message if the license is not active.
This would indicate that communication to our license server is not working or more likely blocked by WP Cerber at the time of that screenshot.
Regarding the AM360 license check, it works when the admin is logged in. But to a logged off user or at the alternate login/logoff screen it is apparently blocked, thus the maintenance mode message from AM360 (which prevents subscribers from logging in).
From AM360 Support:
If they could explain what changes they had made we could perhaps assist further.
Regarding version 8.4 from your blog:
The custom login page feature has been updated to eliminate possible conflicts with themes and other plugins.
Can you shed any light on this please?
