How to Disable Scripts on a Per Post/Page Basis (Scripts Manager)

We now have a Scripts Manager in the perfmatters plugin. This allows you to disable scripts on a per post/page basis. This is very powerful and can drastically increase the speed on your WordPress sites (especially your homepage). A few examples of what this can be used for:

  • The popular Contact Form 7 plugin loads itself on every page and post. You can easily disable it everywhere with one click and enable only on your contact page.
  • Social media sharing plugins should only be loaded on your posts. You can easily disable it everywhere and load only on post types, or even custom post types.
  • The Table of contents plugin (TOC) loads on every page and post. With the scripts manager, you can easily control where you want it loading.

There are thousands of optimizations you can make with this feature. On some of our sites, we instantly decreased our HTTP requests on our homepage by over 10!

FAQS

  • Does it work with caching plugins like WP Rocket? Yes.
  • Does it work with plugins like Autoptimize? Yes.
  • Does it work with hosts like Kinsta and WP Engine and server-level caching? Yes.

Enable Scripts Manager

This is still technically in BETA while we work out any last hiccups. However, we are using this on all of our production sites, so we don’t expect you to find much wrong with it. To enable it, simply click into the perfmatters plugin settings and click on the “Extras” tab. Then enable the Scripts Manager.

Using the Scripts Manager

After you enable the Scripts Manager you will need to browse to a page or post on your site (it won’t appear in the main WordPress admin dashboard), and it will then show in the toolbar of your site.  We recommend browsing to your homepage and starting there.

After clicking on “Scripts Manager” in your toolbar you will be presented with all the scripts, both JavaScript and CSS files, that are loading on that page or post. You then have the following options:

  1. Enabled (default setting)
  2. Disable Everywhere (you can then choose which posts types you want it enabled on, along with the current URL)
  3. Disable only on current URL (this is very useful for using on your homepage)

Many JavaScript and CSS files you should be able to tell what they are used by simply by looking at the name. For example “social_warfare_script” is obviously being used by the Social Warfare Plugin. If you aren’t sure about a particular file, you can always Google it.

After you select and or modify the settings, make sure to hit “Save.” You can then test in Pingdom or a website speed tool to ensure the scripts are no longer loading on the page or post. Make sure to clear your cache first!

And if anything goes wrong on your site visually, you can always re-enable it in the settings to return to normal.
