 * Hey ! I have a major problem with my website.
 * Theme used : Twenty Seventeen
    Plugins : Akismet, amr shortcode any widget, Facebook
   Open Graph, Google+ and Twitter Card Tags, Jetpack, MailChimp for WordPress, 
   Multisite Post Duplicator, OneSignal Push Notifications, Rss Post Importer, Super
   Socializer, Theme Check, WP Super Cache Hostname : shost.ca URL: [ladiascpora.net](http://ladiascpora.net)
   Version of WordPress : 8.4.2
 * Problems encountered :
 * After having set up my site yesterday, I decided today to pass it in “multisite”
   mode to link it with other blogs. The installation seems to be working properly.
   At the end of the installation, I quickly look at how the sites react. If the
   sub-blogs have no problems, my blog (the main blog) has a 404 error for all pages,
   with the inability to modify the settings of Jetpack, saying me : “_Error updating
   parameters. SyntaxError: Unexpected token <in JSON at position 0_“.
 * I do not know what the error is. The change of status (published / draft), URL,
   creation of new pages always results in a 404. What is this due?
 * This change involves the modification of two files:
 * **htaccess**
 *     ```
       RewriteEngine On
       RewriteBase /
       RewriteRule ^index\.php$ - [L]
   
       # add a trailing slash to /wp-admin
       RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
   
       RewriteCond %{REQUEST_FILENAME} -f [OR]
       RewriteCond %{REQUEST_FILENAME} -d
       RewriteRule ^ - [L]
       RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
       RewriteRule ^(.*\.php)$ $1 [L]
       RewriteRule . index.php [L]
       ```
   
 * **wp-config**
