Hi @jemoreto
Looking at the error, I think it’s because of the translation file for select2. Did you set a different language for your website? Could you reproduce the issue when you set your website to English?
If that doesn’t work, could you please try to reproduce the issue on one of the WordPress’ stock themes (like Twenty Fifteen) with other plugins deactivated? If it disappears, then you can activate the theme and plugins one by one to see which one causes the issue.
If the issue persists, could you please submit a new ticket and provide temporary admin credentials in it? Also, please explain the issue again or include the link to this thread.
Thanks!
