Hi all

I have my dot files in orgmode format and have been using it for a year or so with great success. today i noticed that code block (conf blocks) that i used to tangle recursively have stopped working and i get this error

org-babel-execute-src-block: No org-babel-execute function for conf!

this is an example of how the code block looks
