I got a message from WPExplorer Team:
There was a small bug in the theme, please re-download and update the theme via FTP. The main file affected was js/global.js
Works fine now!
Hello Eetheart,
Same problem here with the Tetris Theme, the menu doesn’t work on tablet & mobile. Yours however seems to work fine by now, so maybe you can help me out here?
Thnx!
