conversion rate 30 days Conversion Rate 30 days

[PaulGrei]

Evening folks.

Installed a fresh prestashop 1.7.4.2 and i cannot preview "Orders" section. I get an error: 

Conversion Rate 30 days

Oops! An Error Occurred

The server returned a "500 Internal Server Error".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

Any ideas why? I tried google but no one seems to have this issue. Server running on Ubuntu 16.04 and MariaDB.

Also some sort of failure loading invoice aswell. Pictures included.

I did the install following this guide. https://www.linode.com/docs/websites/ecommerce/how-to-install-prestashop-on-ubuntu-16-04/#prepare-environment-for-prestashop-and-install-dependencies

Waiting for your magical powers to save my day.

Could it be an error because i am using 7.0 php version?

Kindly check the error log for the details of the error OR enable the debug mode from the backend to check the details on the error on the screen.

Well found a solution to this problem.. Needed to do this command in Ubuntu 16.04 .. 
 

sudo apt-get install php7.0-mbstring

 

and RESTART THE server
