Hi @nicolaslopezj,

After updating the roles to version 2.0.3 last night,I get this error on the console when i tried to update any collection.

Exception while invoking method '/products/update' TypeError: Object function (a) {                                                     // 2   // 10
I20151130-04:38:40.607(8)?   return this.filter(function(i) {                                                       // 3   // 11
I20151130-04:38:40.607(8)?     return a.indexOf(i) < 0;                                                             // 4   // 12
I20151130-04:38:40.607(8)?   });                                                                                    // 5   // 13

How do i downgrade the version before the upgrade? I forgot the version number before the upgrade.

Thanks,

I got managed to downgrade to 2.0.2 on versions folder inside .meteor. Everything works fine now.
