# Access denied. Invalid request.

 * Hello,
 * since the automatic **update of Advanced File Manager from version 5.4.12 to 
   5.4.13**, write operations in the frontend file manager no longer work on our
   WordPress site.
 * The file manager itself loads correctly. Users can access their assigned personal
   directories and read permissions are working as expected. The directories also
   have the correct filesystem permissions.
 * However, any attempt to perform a write operation, for example creating a new
   folder, fails with the following message:
 * **Access denied.
   Invalid request. Please reload.
 * I can reproduce the issue with different WordPress users and different personal
   directories, so it does not appear to be related to a specific user or directory.
 * The AJAX request for creating a directory is sent correctly, for example with:
 * `cmd=mkdir`
   `name=Neuer Ordner``target=l1_Lw`
 * The server responds with:
 * {
   “error”: [“errPerm”,“Invalid request. Please reload.”],“csrfReload”: true}
 * The initial request to the file manager works correctly and reports the root 
   directory with:
 * `read: 1`
   `write: 1``isroot: 1`
 * The problem appeared immediately after the automatic update from **Advanced File
   Manager 5.4.12 to 5.4.13 on August 14, 2026**. The setup and directory permissions
   had not been changed.
 * This looks like a possible regression in version 5.4.13, potentially related 
   to the CSRF/security handling of write requests.
 * Could you please check whether this is a known issue with version 5.4.13?
 * Thank you.
 * Best regards,
   Reiner

 * Hello [@reinergruhle](https://wordpress.org/support/users/reinergruhle/) ,
 * Thank you for the detailed report and for providing the relevant AJAX response.
   We apologize for the inconvenience caused following the update.
 * We have tested the reported behavior on our end but have not been able to reproduce
   the issue so far. To help us investigate this further, could you please provide
   the following details?
    - **WordPress version**
    - **PHP version**
    - A **short screen recording** demonstrating the issue, including the steps 
      taken to create a new folder and the resulting error.
 * The recording will help us better understand the exact workflow and identify 
   whether there is anything specific to your environment contributing to the issue.
 * Thank you for your cooperation. We look forward to reviewing the additional information
   and investigating this further.

 * Hi [@mubashirbutt](https://wordpress.org/support/users/mubashirbutt/),
 * unfortunately, I’m still facing the issue.
 * Meanwhile, I was able to narrow it down: The issue only occurs in the frontend.
   In the backend, Advanced File Manager works fine.
 * Please note that the WordPress version has meanwhile been updated to 7.0.4.

 * Hi [@mubashirbutt](https://wordpress.org/support/users/mubashirbutt/),
 * I did some further testing and found some additional information that might help
   to narrow down the issue.
 * The problem is reproducible in different browsers. I have now tested it with 
   Vivaldi as well, with the same result.
 * When trying to create a new folder in the **frontend**, the AJAX request to
 * `/wp-admin/admin-ajax.php?action=fma_render_secure_auth`
 * with `cmd=mkdir` returns:
 * `403 (Forbidden)`
 * The console then shows:
 *     ```wp-block-code
       elfinder debug: [error] [fma_ui_VSxSaBMVoH8xNgZik]
       Zugriff verweigert.
       Invalid request. Please reload.
       ```
   
 * The relevant request contains, among other parameters:
 *     ```wp-block-code
       cmd=mkdir
       name=Neuer%20Ordner%201
       target=l1_Lw
       ```
   
 * As mentioned before, Advanced File Manager works correctly in the **WordPress
   backend**. The 403 error occurs only when performing write operations through
   the frontend file manager.
 * So at this point the issue appears to be specifically related to the frontend`
   fma_render_secure_auth` request and is not browser-specific.
 * I hope this additional information helps with the investigation.
 * Regards,
   Reiner
