This sounds like some other plugin maybe interfering with it. Try disabling them one by one or it could be a plugin in mu-plugins.

I’ve ran into these issues from time to time and realized that I needed to manually upload the plugin because installing it through the plugins page caused it to not fully install.

Would clearing your browser’s cache work?

I kind of figured it may be a plugin. Since I don’t use it, the only think I can suggest is to contact the developer and let him or her know that the plugin causes issue with the Network Admin page.

It must be a plugin issue. Through FTP rename plugins folder to plugin and see if the site comes back. If so, visit the plugins page, then rename plugin back to plugins. Try activating plugins one by one and checking the site as well in the process until you figure out which plugin caused the site to go down.

Did you activate a plugin sometime in between the process?

I think I understand. Does this page help you to accomplish your goal?

Are you able to check the error logs?

Are you using a control panel for your hosting account like cPanel or Plesk? If so, you can go to the file manager and change a permission for the uploads folder.

Upload a php file to the root of your site and call it info.php. In this file add:

<?php phpinfo(); ?>

Make note of what version it states and where the php.ini file is located.

That’s what I am confused about. What settings are you referring to? The only setting that would need to be set for each blog is the mapped domain.

You should be installing this plugin manually and not network activate it. Have you followed the instructions on this page: https://ottopress.com/2010/wordpress-3-0-multisite-domain-mapping-tutorial/

So, are you still on the same server or have you moved? If you moved, did you do a backup of all your files and then uploaded them to the new server?

You or a client don’t need to know HTML to add content to the editor. If you are good at Microsoft Word, then you already know how to use the editor. Google search pulls up a few websites that go into depth about using WordPress as a CMS: https://www.google.com/search?sourceid=chrome&ie=UTF-8&q=wordpress+as+CMS

You can still use the same facebook file and just overwrite that particular section with the code from pastebin.
