Permissions error from zsh

zsh-error.txt

[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxr-x   7 joshukraine  admin  224 May  2 07:35 /usr/local/share/zsh
drwxrwxr-x  12 joshukraine  admin  384 May  2 07:33 /usr/local/share/zsh/site-functions

[oh-my-zsh] For safety, we will not load completions from these directories until
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
[oh-my-zsh] See the above list for directories with group or other writability.

[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh]     compaudit | xargs chmod g-w,o-w

[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]? 

Lately I've been getting the above error after installing zsh with Oh My Zsh on macOS.
