ReferenceError: geodir_advanced_search_js_msg is not defined

Hi,
we’re facing some issues with the Advanced Search Plugin:
in any Listing page, the jQuery code breaks with the following warning:
ReferenceError: geodir_advanced_search_js_msg is not defined
We can’t see the listing image viewer, the map, the wordpress admin bar and can’t leave a review (the rating system is frozen).
We tried to deactivate the plugin, but we get another error related to the review plugin:
ReferenceError: geodir_reviewrating_all_js_msg is not defined
We also tried to run GDTools (it worked fine) but the javascript warning is still there.
Can you help us?
P.S. we do not run any javascript custom code

Thanks,
Daniele C.
