(Excuse me... wrong button....) Hello all and thank you in advance. I'm totally beginer in PHP . I'm developing: http://www.my3dgis.es/visor/visor.htm# At Options > Herramientas > Búsqueda en Catastro the application shows a form (ExtJS). In this form, the combobox Provincias should be loaded using: http://www.my3dgis.es/visor/php/provincias.php However, using Firebug i can see that call to php/provincias.php always shows 403 (403 Forbidden). I don't know where the problem can be... this application is working ok for me at localhost.... Thank you in advance. Jesús de Diego
