PHP/Mysql database website repair

This project is repair of a Content management system database that worked at one host and when the files were moved parts won't work any longer. It may be as simple as a permissions issue. I am not qualified enough to tell. I can create a page on the backend and see it but it will not appear on the website. I know this site worked for a long time on the same type of server. The message I got from my web host is as follows: On further checking the problem, it seems that the problem is with the code in the file "[login to view URL]". The data entered through the PHP files are not properly been inserted in the database which is causing the problem. ## Deliverables I will give you all the files with the database to work on. I will take the files upon completion and upload them to make sure they work. The worker must provide clean code so as not to be attacked by sql injections or other hacking methods.
