Hello, I am new to setting up websites etc but I had no problems installing OpenCart and a MYSQL Server using justhost.com. I have finished by website but out of nowhere the "checkout" and "basket" buttons get the error in my topic.

Here is an error log, I apologise about being clueless about this but I don't want to re-do my whole shop again if I delete and reinstall OpenCart. Also sometimes my website and admin panel are really slow and sluggish, is this my host or my settiings?

Thanks,
Lequinc

Make sure the following folders have 777 permission:

image/
image/cache/
image/data/
system/cache/
system/logs/
download/
config.php
admin/config.php

I can change the file attributes, what do you mean by 777? I see a Numeric Value field here and Owner, Group and Public permissions. Once again sorry for my low knowledge on this subject.

I see what you mean now, thanks m8.

Okay, it didn't fix it. I still have the The page you requested cannot be found! error on both the basket and checkout.

Thanks for trying though,
Lequinc

will you give me the url so i can look at it?

it is www.lequinckeys.com

I know how to fix it, but it is hard to explain. The only thing would be creating a temporary ftp account and pmming me the username and pass so i could do it.

this ftp account is limited to a specific folder. please give me access to the home folder

Problem resolved thanks to btilm, thanks again m8.
