What is the version of PHP your server is using?
What version of prestashop?
Did you put your shop in debug mode?
Follow this post to try putting the shop in debug mode ->
Do you have a backup of the site and database?

Hello,
Thank you for your reply.
I am using PHP 7.1, I can't remember the exact ps version - I think 1.7.
As I can't access the back office side I manually cleared the following folders:
cache/smarty/compile
cache/smarty/cache
img/tmp
My shop is already in debug mode - if I change define('_PS_MODE_DEV_', true); to false I just get an HTTP Error 500.
I don't have a backup but my host does take regular backups.
Many thanks
