if I update, it will mess the whole thing up and I would have to start all over again.
I did that before and my whole website was deleted with all my pictures.
I have to repeat Phil's advice - updating isn't a choice - the site will break when your provider upgrades PHP levels - or get hacked...
1.4 releases are too old.
Take a look at the upgrade docs - 1.4 to 1.5 isn't a hard upgrade. You do need to address any plugins you are using - or mods you might have made directly to CPG code.
I used this code
$objCpm = new cpm("./gallery/cpmfetch/cpmfetch_config.php");
You need to adjust the code copied from the install page to reflect where you are calling it from - that was an example 'if your gallery was located at ./gallery....'
Your gallery is installed at the website root - and that is where you are calling cpmfetch from - so the code would be:
$objCpm = new cpm("./cpmfetch/cpmfetch_config.php");
