 * After updating the Cookies and Content Security Policy plugin, I’m encountering
   the following error:
 * Error Stack Trace:
 * wp-content/plugins/cookies-and-content-security-policy/inc/settings-cacsp.php:
   138
   WPForms\ErrorHandler->fallback_error_handler()wp-content/plugins/wpforms-

   plugins/wpforms-lite/src/ErrorHandler.php:271WPForms\ErrorHandler->fallback_error_handler()

   cacsp.php:138cacsp_options()wp-includes/class-wp-hook.php:341do_action(‘settings_page_cacsp_settings’)
   wp-admin/admin.php:264
 * The error appears to be triggered when accessing the plugin settings page and
   seems to involve a conflict with the WPForms plugin’s error handler.
 * Please advise on how to resolve this issue.

 * The stack trace alone isn’t enough to pinpoint the root cause because it doesn’t
   include the actual PHP error message.
 * Please share the exact error text (the “Fatal error/TypeError/Warning” line) 
   and where you saw it (screen vs debug.log). Also confirm:
    1. WordPress version
    2. PHP version
    3. Which admin page/tab triggers it (Settings > Cookies and Content Security Policy,
       and which tab)

 * Thank you for your response.
 * Here is the information you requested:
    1. WordPress version: 6.9.1
    2. PHP version: 8.1.31
    3. Admin page/tab: Settings > Cookies and Content Security Policy > Design tab
 * Error messages (detected via Query Monitor):
 * Warning 1:
   include_once(settings-cacsp-tab-design.php): Failed to open stream:
   No such file or directoryLocation: wp-content/plugins/cookies-and-content-security-
   policy/inc/settings-cacsp.php:138
 * Warning 2:
   include_once(): Failed opening ‘settings-cacsp-tab-design.php’ for
   inclusion (include_path=’.:/usr/share/php’)Location: wp-content/plugins/cookies-
   and-content-security-policy/inc/settings-cacsp.php:138
 * Both errors appear when accessing the Design tab in the plugin settings. It seems
   that the file ‘settings-cacsp-tab-design.php’ is missing from the plugin directory
   after the update.
 * Best regards

 * My bad, I forgot to add a new file, that is fixed in the latest version. Thanks
   for the heads up!
