Trouble using subdomains on WP multisite.

Hi everyone,

I have created two subdomains and can’t access them via the WordPress site menu.

I’ve gone through many threads on this topic, tried every suggestion I’ve come across, and nothing seems to work. This includes redirecting to my main domain and redirecting to ../html. Any suggestions will be gratefully appreciated.

My site is https://www.twomarshmallows.net. My .htaccess file looks like this:

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).*) $1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]

When trying to get to subdomain’s dashboard, following error occurs:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

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

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

My hosting site uses cpanel. I’ve created the two subdomains. I tried redirecting the subdomains to the main domain, but to no effect.

Any suggestions? Many thanks!
