Hi Ana,
As per your query, we have reviewed your site and you are using an old version of our theme.
Go to https://www.vwthemes.com/my-account/ with your details. Then go to https://www.vwthemes.com/my-account/downloads/ and download the updated theme.
Then login to your FTP or Cpanel. Go to wp-content/themes and upload the zip file you have downloaded. First rename the existing theme folder then extract the newly uploaded theme.
If you need any other help please let us know.
Thanks
