bbPress, a popular forum plugin for WordPress, was originally designed for classic (PHP template-based) themes. With the introduction of Full Site Editing (FSE) and block-based themes in WordPress, significant changes were made to how templates and content are structured. As a result, bbPress often does not display correctly—or at all—when used with block-based themes. Here’s why:
Table of Contents
Key Reasons for Display Issues
- Template Incompatibility:
Block-based themes use a different templating system (HTML files and the Site Editor) compared to the classic PHP templates expected by bbPress. bbPress tries to load header, footer, and sidebar templates that do not exist or are structured differently in block themes, leading to missing layouts, broken pages, or even the “White Screen of Death” (WSOD). - Index.php Fallback:
When bbPress cannot find the expected templates, it often falls back to the theme’sindex.php, which in block themes is typically empty or minimal. This can result in blank pages or incomplete forum displays. - No Native Block Support:
As of early 2025, bbPress does not provide native blocks for the block editor, nor does it ship with templates designed for block themes. This further limits its compatibility and flexibility within FSE environments.
Workarounds and Solutions
- Enable bbPress for Block Themes Plugin:
The community has developed plugins specifically to bridge this compatibility gap. The Enable bbPress for Block Themes plugin modifies the template hierarchy and provides a dedicated “bbPress content” template, ensuring bbPress content displays correctly within block themes. This plugin also allows you to edit bbPress templates in the Site Editor, giving you more control over layout and appearance. - bbPress Style Pack Plugin:
Another popular workaround is the bbPress Style Pack plugin, which includes fixes for block theme compatibility and offers some styling options. Users have reported success enabling “Theme Support” within the plugin’s settings, which helps bbPress display properly in block themes. - Custom Template Tweaks:
Some users have resorted to custom code or copying classic theme templates into their block theme directories, but this is generally a temporary or less robust solution.
Important Notes
- Styling Still Required:
These compatibility plugins generally do not provide CSS styling. You may need to add custom CSS or use additional plugins to make bbPress visually match your site. - No Block-Based bbPress Views:
bbPress still does not provide native blocks for forum content. You can use shortcodes within the block editor, but full block-based customization is not yet available.
Summary Table: Issues & Solutions
| Issue | Cause | Solution/Plugin |
|---|---|---|
| Blank pages or WSOD | bbPress can’t find classic templates | Enable bbPress for Block Themes plugin |
| Header/footer/sidebar missing | Block themes use different template files | bbPress Style Pack plugin, custom templates |
| bbPress content not styled | No CSS provided by compatibility plugins | Add custom CSS or use a style plugin |
| No block-based forum layouts | bbPress lacks block support | Use shortcodes or wait for future updates |
Conclusion
bbPress does not display properly on block-based (FSE) themes because it relies on classic theme templates that are missing or incompatible with the new block theme structure. The best solutions currently are to use the “Enable bbPress for Block Themes” plugin or the bbPress Style Pack plugin, both of which address template compatibility but may still require additional styling for a seamless appearance.
