Error on http://test.csswg.org/harness/submit

*Dears,*

*I was running HTML test on
http://test.csswg.org/harness/testcase?s=CSS21_HTML&r=125&o=1&u= but when I
click on "test pass" the following error occurs :
*

*"**ERROR: Posted data is invalid. *

*File: /sites/
csswg.org/test/htdocs/harness/lib_test_harness/class.dynamic_page.phi *

*Line: 131 *

*Context: Array ( [error_msg] => Posted data is invalid. [error_type] => 256

Have a nice day,

Nicolas
