Dear Mike,
thanks for the instructions, but in this order it doesn´t work.
When we follow the procedure the themes refuses an update and gives out the following error message:
“Das Paket konnte nicht installiert werden. Dem Theme fehlt das Stylesheet style.css.” – in Englisch: The package couldn´t be installed. The theme is missing the Stylesheet style.css.

What can we do? Please help.

Martin
