Thank you very much for choosing our theme and for contacting us.
Please deactivate the plugins not related to the theme and switch to the parent if you activated the child theme. If the problem persists, insert the site admin access into the Private content below the message area and advise which demo you want to upload. We will take a closer look at the case.
theme message : API server is temporarily not available. We are moving our API to a new server. It may take up to 48 hours to update all DNS zones and then you will be able to activate the theme.
Take our apologies for any inconvenience. Please, send us your admin access so we can check and try to activate the theme for you. Please, include your purchase code as well.
We would be glad if you can change your rating on ThemeForest while we are here to help you.
