blanc page after submitting create account

[selectiveform]

I am using the french language pack and everything is working fine up until I try to create a new user account. After filling out everything and when I click create new account, I get a blanc page. When I verify the account creation in the admin there is nothing been created.
In the error logs I have the following:

[12-Mar-2015 09:12:48 America/Chicago] PHP Warning: constant(): Couldn't find constant BOX_HEADING_ADMIN_ACCESS in /home/tattougr/public_html/marezo.com/zcadmin/includes/functions/admin_access.php on line 854

on the mention line above I have the following:

$retVal[$result->fields['menu_key']] = constant($result->fields['language_key']);
$result->MoveNext();
I also checked the language file create_account_success.php and everything is fine there no coding error.

Did anyone experience this issue with the french language pack? if yes how did you resolve it? Or anyone has an idea on how to resolve this please? Thanks for looking.

Sorry to tell you this, but it looks like you may have more than one problem to resolve.

The "PHP Warning: constant(): Couldn't find constant BOX_HEADING_ADMIN_ACCESS" really is just a 'warning' (not an error) and this wouldn't (or shouldn't) be causing a blank page issue.

To fix this warning is probably just a matter of adding the 'define' into the admins french language file.

define('BOX_HEADING_ADMIN_ACCESS', 'Gestion de l'accès admin');

My only concern here is that if this 'define' is missing, there are probably others missing as well.

As for the blank page.. This is going to be a little more difficult to resolve without a bit more information. Were there any other 'error logs'?

You'll be looking for one that reads something like

"PHP Fatal Errror: blah blah blah blah"

Hope this is of some small help.
