Customizer not working

Hi,

when I try to customize the theme via the admin area I would get:

customize.php?theme=point&return=%2Fwp-admin%2Fthemes.php:4489 Uncaught SyntaxError: Unexpected token <

in my debug console. I would also get:

s[“point_trending_section”] = {“value”:”0″,”transport”:”refresh”,”dirty”:false};

<b>Warning</b>: sprintf() [function.sprintf]: Too few arguments in <b>/home/****/***/wp-includes/theme.php</b> on line <b>874</b>
s[“point_trending_cat”] = {“value”:false,”transport”:”refresh”,”dirty”:false};

in further reviewing the debug console of the application.

Do you happen to have reports for similar issues?

Thanks,
Kiril I.
