No working multisite in Network Dashboard menu, but DB-Tables created- wp 5.1.1.

[awlizw]

Is here anybody has the same problem? My WP does not activate the Dashboard Menu "Sites" nor "Network Admin", but multi site is installed into mysql database.

I set up a fresh WP installation to create a network with multi sites and started simple with an empty site, no plugins and theme "Twenty Nineteen".
I use xampp and set up subdomains which are working.
I went through normal activation WP_ALLOW_MULTISITE following the manual process step by step: ​https://codex.wordpress.org/Create_A_Network
So far everything was fine, but WP-core doesn't activate the Dashboard Menu "Sites" nor "Network Admin" ...

The Database seem to be installed correctly.

Tools>Network Setup->Create a Network of WordPress Sites
"Warning: An existing WordPress network was detected."

but contradictory wise:

​http://xxx/wp-admin/network/about.php
"Multisite support is not enabled."

​http://xxx/wp-admin/network/upgrade.php
"Sorry, you are not allowed to access this page."

No further console errors.

The Problem seem to me to be the hook for admin main menu?

Hi @awlizw,

Welcome to Trac!

This Trac instance is for development of the WordPress Core software. From the details you have provided, it does not seem like this is a bug in WordPress but rather with your local configuration. I recommend opening an issue in the ​WordPress.org support forums. That location is much better suited for requests like these.

Finally I found myself what was missing. Your documentation in WP CMS and online (above) is old and incomplete.
Beside "define('WP_ALLOW_MULTISITE', true);"
has to be placed afterwards
"define('MULTISITE', true);"
to just activate the MENU!
Well,by going ahead more error come, css is not loading and so on

Hi @awlizw,

The codex is actually outdated. I recommend that you use the Help Hub instead. Here is the page related to multisite: ​https://wordpress.org/support/article/installing-multiple-blogs/#multisite-feature

Please utilize the support forums for further assistance on getting up and running with multisite.

To start the multi-site installation process, the user adds a define for WP_ALLOW_MULTISITE to wp-config.php.

After the multi-site installation process has completed, WordPress tells you to update wp-config.php with an additional number of DEFINE statements.

I have found, at this point, if you do not remove the original WP_ALLOW_MULTISITE definition, the "My sites" menu never shows up (WP 5.2.2), and there is a permissions error if you try to access the network admin URL.

Please update the WordPress instructions to tell the user to remove WP_ALLOW_MULTISITE from wp-config.php at the end of the multisite installation process. Currently the instructions are only to add the additional define statements.

I have a feeling that may resolve this issue.
