首先，尝试使用原始管理员角色.

First of all, try the original administrator role.

如果登录，则自定义角色存在问题.

If it logs in then there is a problem with the custom role.

我认为1.4x中的自定义角色要求检查全局搜索.否则，可能在etc/config.xml

The custom role I think in 1.4x requires global search to be checked. Otherwise there maybe a module that doesn't have permissions XML setup correctly in etc/config.xml
