Visual Editor – Visual Tab Not Working, Query String Adjustment Required

Hey,

So long story short…
– server got hacked, 64decode content injection
– cleared, incoming spam links using /? query string
– blocked it with htaccess, also blocked post/page previews
– new code allow page/post previews, but now blocks visual tab

Here’s the latest rendition of the code I’m using:

<IfModule mod_rewrite.c>
RewriteCond %{QUERY_STRING} ^[\-/A-Z0-9]+$ [NC]
RewriteRule (.*) - [R=404]
</IfModule>

This code doesn’t block query strings with ‘=’ in them, which is used by wordpress for previews.

So, I guess there should be a way to modify it to allow both the previews and the visual editor requests to past through.

Help?

Thanks!
