Hello.

I haven't been to find posts for my specific question: How do I completely change the working directory of Cubecart?

I currently have all my Cubcart files under htdocs. I want to move the whole store to /htdocs/foldername. Can this be done easily?

Thanks.

Very.
1. Move the whole thing.
2. Edit /foldername/includes/global.inc.php to reflect the new position.

That is, just add "/foldername" to the end of:
$glob['rootDir']
$glob['storeURL']

and "foldername/" to the end of

$glob['rootRel']

Then in admin, change the same things for your SSL settings.

Done.
