Hi Luis,
From what I can remember my co-worker created a custom profile field and made them required.
I turn on the debugging and I get this error below:
QuickForm Error: the rule does not exist as a registered rule Rule '' is not registered in HTML_QuickForm::addRule()
Backtrace :
Array ( [0] => Array ( [file] => F:\mighServer\Apache\Apache24\htdocs\moodle\moodle\lib\pear\HTML\QuickForm.php [line] => 1990 [function] => PEAR_Error [class] => PEAR_Error [type] => -> [args] => Array ( [0] => the rule does not exist as a registered rule [1] => -2 [2] => 16 [3] => pear_handle_error [4] => Rule '' is not registered in HTML_QuickForm::addRule() ) ) [1] => Array ( [file] => F:\mighServer\Apache\Apache24\htdocs\moodle\moodle\lib\pear\PEAR.php [line] => 531 [function] => HTML_QuickForm_Error [class] => HTML_QuickForm_Error [object] => HTML_QuickForm_Error Object ( [error_message_prefix] => QuickForm Error: [mode] => 16 [level] => 1024 [code] => -2 [message] => the rule does not exist as a registered rule [userinfo] => Rule '' is not registered in HTML_QuickForm::addRule() [backtrace] => Array *RECURSION* [callback] => pear_handle_error ) [type] => -> [args] => Array ( [0] => -2 [1] => 16 [2] => pear_handle_error [3] => Rule '' is not registered in HTML_QuickForm::addRule() ) ) [2] => Array ( [file] => F:\mighServer\Apache\Apache24\htdocs\moodle\moodle\lib\pear\HTML\Common.php [line] => 100 [function] => raiseError [class] => PEAR [object] => PEAR Object ( [_debug] => [_default_error_mode] => [_default_error_options] => [_default_error_handler] => [_error_class] => PEAR_Error [_expected_errors] => Array
)
)
.....Have not changed anything on my part but let me check and see what could the error be.
