Problems changing install directory

[double-happiness]

I followed the instructions on https://www.zen-cart.com/tutorials/i...hp?article=122 to change my install directory to the root of my site, it seemed to work OK at first, but now I am just getting...

Sorry!
There seems to be a problem connecting to our database. Please give us a few minutes to remedy the problem. Thank you.

I still have the original install in place as I didn't want to delete it until I was sure the new install was OK, what is puzzling me is after I login to my new Zen Cart admin directory, the url has /catalog/ and all the links are to /catalog/ (the old install dir.), so it seems I am being re-directed to the old admin area.

NB there is also a setting in my web-host control panel to specify the installation directory, but changing that didn't fix the problem.

Any help please? thanks
