[jQuery] $().load( ) issue: "url has no properties"

[jQuery] $().load( ) issue: "url has no properties"


Anyone knows what this error message means ?
"url has no properties" pointing to jquery.js line 2401, which is
the $().load() ajax call definition. (and specifically: that line:
        var off = url.indexOf(" "); )
i don't understand the error because i'm providing an URL and it
works correctly out of the ajax call. In fact that function was
working before i made some severe changes elsewhere in the code.
Any hint / directions where to look for errors ?
Thank you,
