on_document_load.js

. The odd thing is that I only see this error on the live environment, the local environment has no such error.

That particular line contains:

bigStarsPath : geodir_all_js_msg.geodir_default_rating_star_icon,

The error shows up on these two pages:
http://highway.bigrigmedia.com/places/palm-canyon-hotel-rv-resort/

http://highway.bigrigmedia.com/explore/

this error can happen if your server hasn’t installed mb_stringtolower extension on the server.
To avoid this error you can add a function to geodirectory:

if (!function_exists(mb_strtolower)) {
function mb_strtolower ($string, $encoding=”) {
return strtolower($string);
}
}
