When I submit a question (http://www.diggs.co.za/questions) I get the following message:

Error opening database file (/usr/www/users/diggsxxsqt/media/com_cjlib/geoip/GeoLite2-City.mmdb). Is this a valid MaxMind DB file?

Item successfully submitted.

The question is stored and available in the backend, but I don't want users to see this message. 

Then, when I submit an answer, I get the same message, but I am also taken out of the page back to the homepage.  I don't want the user to be

re-directed to the home page every time they've posted an answer.

How can I solve these problems?

The site's Global Configuration has been set to show no error reporting.

Thank you
