I've got a fresh WordPress 3.2 site and also have triggered multi-site for this. I'm hosting this on the shared CPanel account and also the WordPress install is incorporated in the root /public_html folder. I've it looking for wildcard subdomain blogs.

The issue is that I've been getting lots of random Internal Error 500's (every ten minutes), so my host stated that it's due to .htaccess. So that they erased .htaccess and today my website no more will get the mistake 500's.

Why could this be happening? Any applying for grants exactly what the problem might be and just how to repair it? Any help or advise is greatly appreciated.

Here are the only real logs I've from CPanel. Just a lot of file not found errors, that we can't realise why this could cause it. It may sound nearly the same as this but no resolution was determined there: http://wordpress.org/support/subject/multisite-default-htaccess-rules-cause-infinite-loop-1

Here's my .htaccess incidentally:

# BEGIN WordPress

RewriteEngine On

RewriteBase /

RewriteRule ^index.php$ - [L]

# submitted files

RewriteRule ^files/(.+) wordpress-includes/ms-files.php?file=$1 [L]

RewriteCond % -f [OR]

RewriteCond % -d

RewriteRule ^ - [L]

RewriteRule . index.php [L]

# Finish WordPress
