I followed the tutorial by pginpa for installing onto 1and1.com and included his .htaccess file. Everything loaded up fine and I had a good time working with C5. What I didn't realize until I started getting phone calls from my clients was that by installing the .htaccess file in the root directory it disables my other non-C5 websites...something about the 1st line containing index.php.

So, I moved the .htaccess file to the C5 folder. My other website now work but the C5 one does not. Is there a modification I can make to the .htaccess file that will let it peacefully coexist in the root directory of the server with my other sub-directories?

I appreciate any help I can get on this. I'm really digging the C5 experience after that migraine-producing Joomla
