Vim <CR> mapping not working? - mapping

Question

I just recently got into using vim, and am having great fun adding load of useful plugins. Problem is that at some point during setting up all of my plugins I hadn't noticed that the mapping for the enter key stopped working properly. In insert mode, when I press enter, if there is currently no auto-complete menu, instead of creating a newline it prints this:
pumvisible() ? "\" : "\"
Here is my vimrc:
"{{{Auto Commands

I'm new to vim, so if there is anything else that is needed please let me know.

Answer 1

Supertab includes a mapping to <CR> that conflicts with the "inoremap <expr> <cr> ..." mapping. Specifically if supertab is loaded after the other it breaks it. If the inoremap mapping comes after supertab is loaded then it works.
You could make your inoremap mappings after supertab by putting them in .vim/after/plugin/mappings.vim or similar.

Answer 2

You might try issuing the command :map <CR>, which will list current mappings for carriage return. If that doesn't help maybe you could try a grep across all the plugin files you have loaded for string that matches map <CR> and/or pumvisible.

Answer 3

What is this mapping supposed to be doing?
inoremap <expr> <cr> pumvisible() ? "\<c-y>" : "\<c-g>u\<cr>"
Seems like that's your problem. Not sure how to fix it, but I'm pretty sure if you take it out and restart, your return key will work again. I don't understand because return accepts the selected completion for me out of the box.
