    I saw the stable release of roundcube 1.7 today, and tried to install it. Apparently they have changed their web structure, and require a /public_html folder be the root of the site, and then it references other files/folders that are above that root folder. This obviously does not work with ISPConfig, as it doesnt let you have 'custom' folders above /web. I tried using apache directives to override it to use /web/public_html as the root, but couldnt get that to work.
    Its rather irritating they made a change like this that entirely breaks roundcube on ispconfig3. Wondering if anyone else has tried this or has a workaround.

    This assumption is not correct. ISPConfig allows you to configure a custom directory in Apache as well as in Nginx using the Apache or Nginx directives field for many years now. For Apache, the directive is named DocumentRoot, you use:

    Code:
    DocumentRoot "{DOCROOT_CLIENT}/public_html"

    Thanks, I had tried that but was having trouble getting it to work. I'll give it another go.

    Could I get a little deeper explanation of what's this change in RC 1.7 means? In the 1.6 version, "/webmail" was just an alias that became available to all domains added to an ISPConfig website as part of the global conf.d/roundcubemail.conf configuration file for Apache. Do I now have to "enable" roundcube for each domain added to server that has v1.7 installed by using the DocRoot directive above? is that directive ADDING another document root, or replacing the existing one? does the conf.d/roundcubemail.conf that we were using for v1.6 need to be changed for 1.7 to make it work globally?
    I've been looking around for an explanation to this, but have only been finding "you have to use public_html" but I've not seen what anyone actually changed to make that work.
    thanks.

    @jnewman67 The first poster manually installed RoundCube into a website, he does not use a standard ISPconfig installation. So any information above does not apply to standard ISPConfig setups. The post title is a bit misleading because it is not about a normal ISPconfig RoundCube installation.

    No.

    Do not add that directive to your website unless you also manually installed RoundCube into that website from source. Above, I answered a specific question about the manual installation of software that the first user made. The answer is specific to his case and manual setup; it does not apply to RoundCube on ISPConfig systems in general that were installed using our install guides or the auto installer.
