This built-in theme feature will cache all dynamic theme styles (for example, generated on custom pages built with WPBakery Page Builder (formerly: Visual Composer) which uses custom styles & colors) so it wouldn’t be executed any time when someone visit your website, but just will be loaded from cache.
This option can be enabled in “Ueldo” – “Theme Options” page in your WordPress admin panel, under “Dynamic Theme Styles Cache” option. You can enable or disable it (default: enabled), and set when cache should be cleared:
- manually only – this is good option when you don’t want to do any changes in your website in the near future. If you’ll do any changes, you can click on “Clear cache now” button to clear your website styles cache and load updated styles,
- all the time when logged in – this is default setting. Your website styles cache will be cleared automatically, all the times when you visiting any page on your website and you are logged in to your WordPress admin panel (as administrator).
