I have a multilingual website using Drupal 7. The 1st développer didn't use Views.
I installed i18n modules (entity translation, etc ) Un templates I have been using variables like $vars['und' ] (for undefined)
I think drupal ran update and now the template system uses $var without the language as key.. I think I activated block translation.. Other thing : (I purged caches) template still work as disconnected user but doesn't work as administrator.
Do you know what's happend ?
Thanks for your help Mario
