javascript problem

Hi,
I'm using zh_osm on my website. It used to work fine. But now the map doesn't show anymore.
I'm getting this error message (regardless ot the browser I'm applying):

Uncaught SyntaxError: Invalid hexadecimal escape sequence

leading to this line in the file:

var icoUtils='http://localhost/mpf6x/administrator/components/com_zhosmmap/assets/utils/';

Any idea what I can do about it?

Probably you have some incorrect custom icon name.
Without link to map page I can't tell more

I can't provide a link, because the website is still locally hosted only.
What do you mean by "custom icon name"?

Do you upload your icons, if yes - probably it have wrong filename.

You can save your page, zip it and mail me to check it: ZhukDL@gmail.com
