[support] Validation error, please try again. If this error persists, please contact the site administrator.

[Julien Jabouin]

Hello,

In Drupal6, in /admin/build/block, when i save the page, i have this error :
"Validation error, please try again. If this error persists, please
contact the site administrator."

In fact i have this error on several D6 themes but not Garland.
So i don't know if it's a error theme or other thing.

Do you have an idea ?

Thanks,
Julien.
