UPDATE

I returned the .htaccess configuration to the suggested subdomains and it continues to work fine, as shown below:

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]

I recommend using this and not the directories I mentioned earlier.

Excellent, I’m glad to hear it.

It’s a relief, I know. hehehe

Hello maybe this will help you.

He had the same problem and this solved it.

We have discovered that the wildcard subdomain for the domain had an incorrect root directory assigned.

Go to your cPanel to the subdomains area and check the following

My mistake:
Subdomains Document Root
*.mywebsite.com /_wildcard_.mywebsite.com

It worked for me:
Subdomains Document Root
*.mywebsite.com /mywebsite.com

Another important thing is that I left the .htacess that is indicated for directories and not the one indicated for subdomains.

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

This worked for me, for multisite subdomains. I do not know why per well it was. Try both.

Good luck ??
