Can't source zgen

[espenol]

When I start zsh, I get the following error messages:

/home/espenol/.zshrc:1: command not found:  source
/home/espenol/.zshrc:4: command not found: zgen
/home/espenol/.zshrc:7: command not found: zgen
/home/espenol/.zshrc:10: command not found: zgen

My first guess would be that my PATH variable is messed up, but if I in the shell write which source it returns source: shell built-in command, so it obviously finds the command. Also, if I insert the comment # Load zgen as the first line of .zshrc, I instead get the error message

/home/espenol/.zshrc:1: command not found:  #

Any clue as to what is happening and how I can fix this issue? I'd like to try out some plugins. Runnig zsh 5.7.

My .zshrc is as follows:

source "${HOME}/.zgen/zgen.zsh"

# if the init script doesn't exist
if ! zgen saved; then

  # specify plugins here
  zgen oh-my-zsh

  # generate the init script from plugins above
  zgen save
fi

Apologies if this is not the correct place to ask.

It was of course because of BOM settings, stupid me. Using :set nobomb in vim solved the issue.
