For some reason, I get no autocomplete on html and css files. All works well with other languages, for example JS, Ruby or Python. I\'ve spent close to 2h today trying to fix it
Check the value of the paste setting
paste
:verbose set paste?
will show you the current value for this buffer as well as which plugin set it last.
In my experience, completion doesn't happen if paste is set. Disable with
:set nopaste
