vacation plugin install error

[Staff]

When I click on the new tab that appears in rouncube after the install instructions I get this:

CONFIGURATION ERROR

Vacation plugin: /ab/ cannot be executed by user ''
Please read the INSTALL instructions!


I guess it is because I dont know what this instruction means and I did not find that specific file if it is supposed to be a specific file for each webmail user:
5) chown $apache_user plugins/vacation/config.inc.php

or is it something else I have missed?

Weird, only pressed the "submit" button once.

I´ll get back when I have it

Rc is the latest, just installed it 1 week ago

I am pretty sure Its the thing I wrote that I dont know what apache user means.. Is it some folder that exists that is assigned to each mail account?

I dont host the mails myself, it is a hosting company link

From what I can tell they use there own custom panel so there isn't any auto-forwarding, vacation messages, or change password plugins that would work.

It may not be important if you aren't hosting.

I'm not sure what the plugin does or how it works as I'm a native Winders administrator. However, the instruction that you aren't understanding is a Linux shell command to change the ownership of that directory to the $apache_user.  $apache_user is the variable that would be assigned the user account that apache uses.
