 * Hello [@lexa1](https://wordpress.org/support/users/lexa1/)
 * We tried to replicate the issue on our end, but we couldn’t notice such an issue.
 * Can you help us replicate the issue on our end? You can provide some steps to
   replicate the issue –
    # Installed (Activated plugins) # Any configurations if
   it’s done # Or if you could provide us a staging site to debug the issue, that
   will be great.
 * For more information about the error and for the troubleshooting steps you can

 * If the issue still persists, you can [open a support ticket](https://wpastra.com/support/free-support/)
   with us from here with this information.
