I've installed and configured Oxwall. Bought a theme, Minimalistic - Dark, from the Oxwall store and installed it. I couldn't use "add theme" because it would go so far as connecting with FTP then gives an error saying the file already exists on the server. I deleted the file then uploaded with Filezilla and extracted the files in the "ow_themes"directory. Now, I go to choose the theme but, unlike the other themes, there is no update or activate button.

I wrote the author of the theme but haven't received a response yet.

Any suggestions?
