eric_cs_chan Thank you very much for the error logs! Interesting, it cannot read the buttonizer_buttons_published in the wp_options table correctly (while it does for the buttonizer_buttons at the preview window).
Can you try going to your database, then to the options table, and search for the option_name: buttonizer_buttons_published .
Does that row exists and does it have content? If so, can you copy the option_value into a textfile and send it to us (per mail or dropbox, what you prefer), then we're able to reproduce the error locally and see if it's also going wrong at our side and debug the code.
Sorry for all these steps, this is the first issue we know of that it's not reading the data at the frontend side 🤔
