zsh themes loaded but not working

I set theme in .zshrc file:

ZSH_THEME="random"

And when open new tab, it shows that new theme is loaded:

[oh-my-zsh] Random theme '/Users/maks/.oh-my-zsh/themes/gozilla.zsh-theme' loaded...
mac

But in fact I dont see any changes in theme.

New tab again

[oh-my-zsh] Random theme '/Users/maks/.oh-my-zsh/themes/crunch.zsh-theme' loaded

and again:

[oh-my-zsh] Random theme '/Users/maks/.oh-my-zsh/themes/tjkirch.zsh-theme' loaded...

But still see the same theme. I have already reloaded mac, but no result. The same result in Terminal and iTerm

Update:

Not all themes fails. This one works: trapd00r but with error: prompt_jnrowe_precmd:3: command not found: zsh_path. Others not working.

Update 2: linuxonly theme works too:

[oh-my-zsh] Random theme '/Users/maks/.oh-my-zsh/themes/linuxonly.zsh-theme' loaded...
mac
maks@Makss-Mac:s047->/Users/maks (0)

but with error:

Can't open perl script "/home/scp1/bin/foopath": No such file or directory

Do you have a custom PS1 that is overriding the prompt from the theme you have selected?

1. Check you don't have any additional lines in ~/.zshrc beyond the default?

   1. Backup your .zshrc
   2. Delete all lines beyond export PATH=$PATH:/…
   3. Reload your Terminal

2. Do you have any plugins that are messing with things?

   • Check ~/.oh-my-zsh/custom/plugins/ for any additional plugins.
   • Remove all your plugins from your ~/.zshrc and reload your Terminal.

3. Check you don't have any additional lines in your ~/.zprofile?

   mv ~/.zprofile ~/.zprofile-bak
   

   …and reload your Terminal. (Put back with mv ~/.zprofile-bak ~/.zprofile)

^{Note: trapd00r and linuxonly show the same errors for me}

Do you have your iTerm profile set to report 256 colors?
