CSS File Regeneration
If you’re using a plugin that logs file changes, you might receive notifications about Widgets Bundle CSS being modified. The Widgets Bundle CSS cache regenerates when any of the following occurs:
- Any plugin is activated or deactivated.
- Your theme is changed.
- SiteOrigin Widgets Bundle plugin update.
- An edit is made to a page using the Widgets Bundle.
Why Aren’t .woff Files Preloaded?
A WOFF file is a web font file created in the WOFF (Web Open Font Format) format, an open format used for delivering webpage fonts on the fly. It is saved as a compressed container and supports TrueType (.TTF) and OpenType (.OTF) fonts and also supports font licensing information.

WordPress, unfortunately, doesn’t currently offer a method for preloading web font files. Preloading can be done by using the below function in a plugin like Code Snippets or inserted into a child theme functions.php file. If using Code Snippets, the below function should be set to run on the website front-end.
