Howdy. This plugin looks really cool, so hopefully this will be helpful information for you.

I installed the plugin yesterday but didn’t have time to do anything with it. During the night cPanel ran its nightly WordPress Updates Digest, and this was in the message.

Updates were not installed for the following items:

1.

I uninstalled the plugin. This was in WP 6.4.3, PHP 8.1, MySQL 8.

Hope that helps you.

Hi there.

Thanks for this plugin.

It worked fine for past week or so. But today our site went down due to the plugin. Here’s some error log info that might be helpful.

[Tue Sep 19 07:21:25.998753 2023] [proxy_fcgi:error] [pid 22494:tid 140021981939456] [client 112.213.42.15:0] AH01071: Got error 'PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function shell_exec() in /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-content/plugins/dynamic-front-end-heartbeat-control/heartbeat-controller.php:408\nStack trace:\n#0 /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-content/plugins/dynamic-front-end-heartbeat-control/heartbeat-controller.php(419): get_system_load_average()\n#1 /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-settings.php(462): include_once('/home/608767.cl...')\n#2 /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-config.php(103): require_once('/home/608767.cl...')\n#3 /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-load.php(50): require_once('/home/608767.cl...')\n#4 /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-admin/admin-ajax.php(22): require_once('/home/608767.cl...')\n#5 {main}\n  thrown in /home/608767.REMOVED.com/gpnhmcjwnz/public_html/wp-content/plugins/dynamic-front-end-heartbeat-control/heartbeat-contr...', referer: https://www.REMOVED/garden-store/filters/use/pasture/

It causes an Apache server error, which standard server message:

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.Apache/2.4.57 (Debian) Server at www.mckaysgrassseeds.com.au Port 80

After host did something with the services on the server, WordPress started to load again, but showing it’s critical error page:

There has been a critical error on this website

The only way to prevent that was the disable the plugin (renaming its folder).

Any thoughts?

Hi!

I just discovered and installed this plugin. I’m new to this heartbeat topic, so I want to confirm is this plugin also dynamically adjusts the backend heartbeats (on the admin area and also when editing).

I have a website where multiple users can create pages and edit them, so it’s important for me to control both the public and backend heartbeats.

Is this plugin meant to do this?

Best regards!

Redis supports multiple databases ( 0 – 15 ). Does this plugin need access to the same redis database as used for the object cache of the website? If yes, then suggest to add a setting for that. For example for the Redis Object Cache plugin it can be set via wp-config by defining WP_REDIS_DATABASE.

Hi,

We installed this plugin today because Cloudways Hosting said that Woocommerce and a half dozen Woocommerce related plugins are causing their servers to crash due to excessive AJAX usage.

As soon as it is activated, the entire front end of the website fails to load, and it looks like this, instad of this.

We were forced to immediately disable the plugin due to this, is there a reason that this is happening?

Thanks!

I’m getting a undefined variable $interval on line 53. Looking at the code I see nothing sets $interval before the if statement.

HI, I currently have WP Rocket installed and the Control Heartbeat section activated to reduce activity in backend, post activity and frontend. Should I deactivate this if I install and activate the Dynamic Front-End Heartbeat Control plugin? Thanks.

Hey! We are using Woocommerce and the Shoptimizer theme that uses a dynamic ajax cart, we also use the Woocommerce REST API to sync products to our store, does this plugin conflict with anything?
