 * **Title:** Solid Security Pro JavaScript Error on WordPress 7.0 Multisite (`CORE_STORE_NAME`)
 * Hello,
 * We recently upgraded a WordPress Multisite network to WordPress 7.0 and are encountering
   a JavaScript error when accessing the Solid Security Pro settings page.
 * **Environment**
    - WordPress: 7.0
    - Solid Security Pro: 9.0.3
    - Multisite: Yes (Network Active)
    - PHP: 8.3
    - Browser: Multiple browsers tested
 * **Error**
 *     ```wp-block-code
       TypeError: Cannot read properties of undefined (reading 'CORE_STORE_NAME')
   
       at /wp-content/plugins/ithemes-security-pro/dist/pages/settings.min.js
       at /wp-includes/js/dist/data.js
       ```
   
 * Full stack trace:
 *     ```wp-block-code
       TypeError: Cannot read properties of undefined (reading 'CORE_STORE_NAME')

       ```
   
 * **Troubleshooting Performed**
    - Updated WordPress to 7.0
    - Updated all plugins to the latest versions
    - Cleared all caches
    - Completed the WordPress Multisite Network Upgrade
    - Resolved unrelated Code Snippets Pro database migration issues
    - Error persists after updates
 * The website itself appears to be functioning normally, but the Solid Security
   settings page throws this JavaScript error.
 * Could you please confirm whether Solid Security Pro 9.0.3 is fully compatible
   with WordPress 7.0 Multisite, and whether this is a known issue?
 * Thank you.

 * Hi [@ricdoe2026](https://wordpress.org/support/users/ricdoe2026/),
 * Thanks for the detailed report, the full stack trace makes this much easier to
   reason about.
 * That error is coming from the React app that powers the Security settings screen.
   CORE_STORE_NAME is the plugin’s internal data store, and the message “Cannot 
   read properties of undefined (reading ‘CORE_STORE_NAME’)” means the settings 
   page tried to read from that store before the JavaScript bundle that registers
   it had finished loading. In other words, one of the settings page script files
   did not fully load or register, so by the time the page asked for the store it
   was undefined. The settings UI is split into several script chunks that all have
   to load together, and if one of them is missing or served in a broken/stale state,
   you get exactly this symptom while the front end of the site stays perfectly 
   fine.
 * WordPress 7.0 only released a couple of weeks ago, so it is the newest core, 
   and these admin React bundles are sensitive to how their JavaScript is delivered.
   The good news is the most common causes of this are on the delivery side and 
   are quick to rule out. In rough order of likelihood:
    1. Stale cached JavaScript from before the 7.0 upgrade. After a major core update,
       the browser and any caching layer can keep serving the old admin scripts, which
       no longer line up with the new ones. Please do a hard reload of the settings
       page (or open it in a private/incognito window), and clear any object cache,
       page cache, and CDN cache. On Multisite, clear these network-wide, not just 
       for one subsite.
    2. JavaScript optimization. Any performance or caching plugin (or a host-level 
       asset optimization feature) that minifies, combines, or defers JavaScript can
       corrupt this kind of split admin bundle and produce precisely this “reading 
       X of undefined” error. If you have anything like that active, please temporarily
       exclude wp-admin from JS minify/combine/defer, or turn that optimization off,
       then reload the settings page. This is the single most likely culprit when caches
       have already been cleared.
    3. Plugin version. The plugin is now Kadence Security Pro (Solid Security Pro was
       renamed). Please confirm you are on the latest available build, since a major
       core release like 7.0 is exactly when compatibility updates land.
 * A few details would help me narrow it down if the above does not clear it:
    - Does the error happen network-wide, or only on a specific subsite (and does
      it occur in the Network Admin as well)?
    - Are you running any caching or performance/optimization plugin, or does your
      host apply asset optimization?
    - Does it persist after clearing all caches with JavaScript optimization disabled
      for wp-admin?
 * If it still throws after caches are cleared and JS optimization is off, please
   grab the browser console with the Network tab open and note whether any of the
   plugin’s settings page .js files return a 404 or fail to load, that will point
   straight at which chunk is missing.
 * Kind regards,
 * Pawel P.
