Blank pages/ cannot make new pages

1) Try resaving permalinks (Yes, I know)

2) What’s in your .htaccess?

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+)  wp-includes/ms-files.php?file=$2 [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]
</IfModule>

# END WordPress

Well the htaccess is right. Resaving didn’t help I take it?

no it did not.

What plugins are on for the child site? Any?

There’s 20 for the network, but none active through the child. Want me to list the network active ones?

Actually, knocked it down to 12….

Just the ones that are network activated, or in MU plugins.

Those are the only ones I’m not familiar with and the others I know mostly work.

ok. still noting.

went ahead and deactivated all of them. Still no effect.

Does it work if you turn OFF pretty permalinks on the sub-site?

By turn off, do you mean set it to default? If not then how do I turn off?

Set to default == off ??

example.com/?p=123 is ‘ugly.’

so far none of this is working.

Thin it may be a server issue?

Did the UGLY permalinks work? You never said if they did.

Have you tried a different theme? Like the default, TwentyEleven theme?
