I fixed it by downloading an archived zip version of 1.0.6 (here). Via ftp I renamed the current Minamaze theme as Minamaze2. I unzipped the 1.0.6 file and uploaded the extracted folder to /public_html/<domainname>/wp-content/themes/. At least my customers can see my website again. Was about to buy the full theme until this error hit. Hope it’s fixed quickly.
