Thread:Project:Support desk/.htaccess problems

In being a complete idiot and new to Mediawiki and websites in general, I attempted to set short URLs for my site.

My WebFTP wouldn't show hidden files, and after downloading FileZilla FTP did it occur to me that in adding a new .htaccess file with the short URL code, I inadvertently overwrote the old .htaccess file in my sites root.

First question - is this bad? I assume it is, and it didn't help sort short URLs... Second question - how do I create a new default .htaccess file to replace the one I overwrote?

Many thanks...
