# Fatal Error on Category Archive Pages – PHP 8+ String Array Offset Issue

 * I’m experiencing a fatal error that prevents one specific category archive page
   from loading. The error is isolated to the PowerPress plugin and only occurs 
   on that particular category, not on other pages or archives.
 * **Error Message:**
 * text
 * `Uncaught Error: Cannot access offset of type string on string in /wp-content/
   plugins/powerpress/powerpress.php on line 537`
 * **Error Location:**
   The error occurs in the `powerpress_header()` function during
   the `wp_head()` action, specifically when the theme’s `header.php` calls `get_header()`.
 * **Call Stack (from Query Monitor):**
    - powerpress_header()
    - wp-includes/class-wp-hook.php:324
    - WP_Hook::apply_filters()
    - wp-includes/class-wp-hook.php:348
    - WP_Hook::do_action()
    - wp-includes/plugin.php:517
    - do_action()
    - wp-includes/general-template.php:3192
    - wp_head()
    - wp-content/themes/astra/header.php:31
 * Setup Details
    - **PowerPress Version:** 11.14.1
    - **WordPress Version:** 6.8.3
    - **PHP Version:** 8.4.13
    - **Theme:** Astra
    - **Affected Page:** Single category archive page (not reproducible on other
      categories)
 * What I’ve Already Tried
    - Checked for plugin updates — no newer version available
    - Cannot deactivate the plugin to test (need it active for podcasting)
    - Query Monitor confirms error originates from powerpress.php line 537
 * Question
 * This appears to be a PHP 8+ compatibility issue where PowerPress is attempting
   to access a string value using array offset syntax. Can you provide:
    1. A patch or workaround for this specific error on line 537?
    2. Information on known PHP 8+ compatibility issues in version 11.14.1?
    3. Guidance on whether this is related to category-specific podcast settings that
       may have become corrupted?
 * Additional Notes
 * The error only occurs on one specific category archive page. All other site functionality
   works normally. The site uses multiple performance plugins (caching, Redis, etc.)
   but the error is specific to PowerPress code execution.
 * **Thank you for your assistance with this issue.**

 * Do you have category podcasting enabled? Are you using that category for a podcast
   feed?

 * Mike, I do have it enabled but I’m not using that particular category. I have
   two other categories I do use. One for my old podcast and one for the new one.
