You also need to define a matching COOKIEHASH for both sites – a random 32 bit string will do. By default, COOKIEHASH is an MD5 hash of the site URL, and is used to generate the default names for all authentication-related cookies. Hence why, at the moment, your cross-domain login isn’t working (the names of … Read more

Set the database user permissions to ‘READ ONLY’ Use a function to intercept all db queries. We used this on our theme demo site to … Read more
In a multisite setup, you need to adjust the upload_path for each individual site through the Network Admin menu. Go to /wp-admin/network/sites.php. Edit the site in question. On the settings tab, you can find the Upload Path setting and change it to whatever you want. You can also adjust the URLs on this page. Look … Read more
In Network Admin > Settings > Domain Mapping > Domain Options, uncheck Remote Login. That should also remove it. In my case, the “script” just retrieves the home page (html), causing a script error and a lot of wasted resources on every page view. Similar complaints in Does Domain Mapping plugin insert javascript on headers?.
I use on the root site a small theme for redirect to the languages. A very small theme for locate the language of the users and redirect to the blog of this language. <?php // Browsersprache ermitteln function lang_get_from_browser($allowed_languages, $default_language, $lang_variable = NULL, $strict_mode = TRUE) { // $_SERVER[‘HTTP_ACCEPT_LANGUAGE’] verwenden, wenn keine Sprachvariable mitgegeben wurde … Read more

Although this isn’t well documented, “Super Admin” is not a role (in that it is not an actual role object). It’s more like a special “status”. A list of users who are Super Admins (also called “network admins” or “site admins”) are stored in a database site-option record called site_admins. Generally, adding a capability to … Read more
If possible, you should try and fix the cause of this error – invalid SSL certificates. But there are some instances where this is not possible or desirable. One obvious one being development sites using a self-signed SSL certs. One way around this is to set $ssl_verify to false before line 1161 of wp-includes/class-http.php: curl_setopt( … Read more
There is currently a bug in the functionality that handles the NOBLOGREDIRECT constant, which causes 404 errors on the main site to be redirected to the value of the constant. Apparently this is the expected behaviour for sub-directory networks (example.com/subsite), but should not take place on subdomain networks (subsite.example.com). There is a WordPress Trac ticket … Read more
