Currently i'm experiencing some problems with the price values that can be set within the search widget. The options given by the widget are all empty.
When i take an look at the source code i see the following PHP warnings,
Warning: number_format() expects parameter 2 to be long, string given in /s01/vgn/website/wp-content/plugins/fs-real-estate-plugin/common_functions.php on line 284
It seems that the values i use (price per square meter, those are lower than 1000) are causing the problem.
Also, the module is trying to load the maps script inside the admin area of wordpress. Don't think it's needed there.
