How can I remove this directory/folder from url with htaccess rewrite?

You can use this code:

Goes in DOCUMENT_ROOT/wedgiecommunity/.htaccess:

RewriteEngine On

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+wedgiecommunity([^\s]*) [NC]
RewriteRule ^ %1 [R=301,L]

Goes in DOCUMENT_ROOT/.htaccess:

RewriteEngine On

RewriteRule !^/?wedgiecommunity wedgiecommunity%{REQUEST_URI} [L,NC]
