 * Hi there,
 * Thank you for writing in,
 * It seems your site is conflicting by other third-party plugins because the theme
   does not have such issues.
 * Could you please check by deactivating all the plugins from your site.
 * Thank you!!

 * Thank you for answering
 * Sorry to say, there is no plugins to deactivate
    I make a new wp installation
   and then installed and activate your theme
 * The only plug in there are is Akismet Anti-Spam and Hallo Dolly, both not activated

 * Do you want me to try and delete them?
 * If you want I can give you access to the admin panel for the site
 * Best

 * I deleted the subdomain and installation yesterday. We have decided to proceed
   with another theme instead.
