Ruby 1.9.3-p194

Rails 3.0.3

I was having libcrypt errors today, and after hours of troubleshooting, I uninstalled rvm, ruby and gems. I reinstalled everything, but now my application throws errors. I made no changes to my code, but this worked fine before reinstallation:

21:             </div>
22: <%- flash.each do |name, msg| -%>

Any ideas? This is a bad RoR day for me.
Thanks in advance. -Katie

Edited to add entire application.html.erb:

    I think the problem is this line:

    <%= link_to_if (current_user.admin == true, "Admin Menu", adminmenu_path) %>

    You don’t need the == true, just: 

    <%= link_to_if (current_user.admin, "Admin Menu", adminmenu_path) %>

    Will be fine. If for some reason you did need check equality, you’d need an extra pair of parentheses, e.g.:

    <%= link_to_if ((current_user.role == "admin"), "Admin Menu", adminmenu_path) %>
