setup instructions for multisite on shared hosting

I'm trying to share my wordpress installation, plugins, and theme for three different domains. I've read through many tutorials, and after a couple of months being unsuccessful I need help. I have multisite installed but I just can't seem to get the mapping done correctly. I think I'm missing a step or two for the cPanel settings.

    Hi there @Kyna

    Welcome to the forums, glad to have you aboard!

    If I understand you correctly, you want to be able to use multiple domain names on the same install of WordPress multisite so that you and/or your users can create sub-sites in your network under different domain names, all sharing the same database.

    If that is the case, you've come to the right place 'cos we have a plugin for that: Multi-Domains:

    As you doing this on a shared hosting platform, be sure to check out the "Potential Issues" section at the bottom of the plugin usage page for some helpful tips on getting it set up right:

    I hope this helps! And thanks for being a member :slight_smile:

    I keep getting this error:

    Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    Hi @Kyna

    I need (primary) to also allow wordpress, plugins, and themes to be used on and - if that makes any sense. Each site having it's own content. I have shared hosting - all three domains are hosted through the same webhost

    For this, you need to use domain mapping plugin. Here is the project and usage page:

    Now let me simplify the procedure.

    For example, your main site is
    You have two subsites:
    These two subsites you want to map with following domains repectively:

    So, if anyone enter in the browser, it should show the site of Same for

    So, there are two scenarios now. Either you own all the domains, or you don't. First I think you own all the domains. site is hosted in a hosting whose nameservers are:

    So, you have entered these nameservers for domain panel. You have to set same nameservers for and domains too.

    Then you will add and domains as add on domain in the same hosting of, and make sure you point them to the wordpress root folder. So that if any one enter or it shows site.

    After that, you will add the domains in corresponding subsites using domain panel plugin, and the mapped domain will start working.

    Now, if you don't own the domains, then you will need a dedicated IP. I know you won't have access to the domain panel of your customers so that you can't set name servers in there. So, you will pass them you IP and they need to set a DNS record for their domain and point to that IP. Only then domain panel will work.

    Hope it helps :slight_smile: Please feel free to ask more question if you have.
