 * Hi [@sayna](https://wordpress.org/support/users/sayna/),
 * I am unable to replicate this on my dev site.
 * Are you using the latest version of CartFlows? Also, please let us know what 
   PHP version are you using.
 * Kind regards,
   Herman 😊

 * Hi,
 * Yes the plugin version is 3.0.0
 * and php version : 8.2
 * Just found out maybe it was due to server caching issues/auto_prepend_file htaccess
   via wordfence.. old recall or something, will update soon if the error persist.
 * Thanks 🙂
