Hello, i'd install simple cache,

This is the error:

Notice: Undefined offset: 0 in simple_cache_user_check() (line 228 of /var/www/vhosts/soportejuridico.com.co/httpdocs/sites/all/modules/simple_cache/simple_cache.module).

This is my Drupal:
Drupal 7.22
PHP: 5.3.3
Other Module about roles:

  • User Permissions 7.x-1.1
  • Roles (Ubercart) 7.x-3.4
  • Node Limit User of Role 7.x-1.0-alpha5

Right now i've disabled the module, and i think can be usefull for me.

Thanks!
