can't save openERP report designer

Asked by Pravitha V

hello i want to customize the reports in openerp and for that i installed base_report_designer and report_designer modules and then a screen comes to save the openerp report designer. but when i press the save as button the following error occurs

File not found
Firefox can't find the file at http://localhost:8080/openerp/form/save ... p_id=False.
Check the file name for capitalization or other typing errors.
Check to see if the file was moved, renamed or deleted.

and another error appears at the terminal:
