If you purchased the theme the company you purchased it from should fix the problem.
Hi Ficelle,
Author Pro is actually a plugin, so it can be uploaded via the Plugins menu in your admin dashboard. As a plugin, you don’t have to worry about any of the issues that come with switching themes. You can just activate it, and all of the features will be added automatically without disrupting your site.
For future reference, as a customer you can always reach us through the Priority Support form.
the problem come from the installer, same issue than the other contributor… my wordpress install is in french.
If you are trying to install Author Pro, please install it via the Plugins menu, not the themes menu.
No worries, let me know if you need anything else.
