If your hosting company told you that, then you should consider moving to a real one (unless you have a really huge and busy site).

Or install and use

https://wordpress.org/plugins/heartbeat-control/

What version of PHP you use ?

Hi @timrodman,

Most of plugins which has some function on WordPress front-end use admin-ajax.php. All ayax ections are made via admin-ajax.php. if you disable it your website will be a cripple website. The wpForo also doesn't have any chance to work on such website.

You should find the plugin who sends lots of requests to admin-ajax.php and disable it. This is the best solution. If you have plugins which do some lifetime functions, you should start checking those first. wpForo doesn't overload admin-ajax.php, it only use admin-ajax.php on like/dislike and other small actions. These kind of actions don't overload AJAX system.

Thank you both.

@anonymous20 - Sorry, I wasn't specific enough. They weren't suggesting to disable the PHP script, but to use the plugin that you mentioned.

@robert - If I use the "Heartbeat Control" plugin and use the "Disable everywhere" option mentioned in this post, will it affect wpForo?

As i said, their suggestion was not a good one UNLESS you run a big anf busy site. But in that case you should change hosting plan, simply.

There is no need to run any such plugin for anything. Maybe for a busy site under a budget hosting plan ? I dunno.

But you don't tell us much about your site ? Big ? Small ? Busy ? Shared Hosting ?
