Information pages - The page you requested cannot be found.

Hi There,
Website got hacked/malware infection and has since been cleaned however now none of the information pages work and am getting error - The page you requested cannot be found.
I am not savy with opencart but have researched the issue and not been able to find same issue in the forum or a resolution that works.
For example I read about SEO requiring value or can cause issues so have checked that but SEO feilds have values.

The information pages and content are there when viewed through admin console/backend just not displaying when visiting the website - so i assume it is a link issue?

This is the site
http://www.fedelejewelworks.com.au/

All information pages are effected - services, diamonds, about us and testimonials

opencart 1.5.2.1

Does anyone have any ideas as to what the issue may be and how i'd fix it.
thanks in advance Mia

Are seo urls switched on? Is the htaccess file in root of the store correct? Was database affected by hacking, esp url related tables like url_alias? Any seo related extensions running that might be impacting on info pages? tried creating a new info page ... does it work?

These are all good places to start.
