Help with PHP files not working correctly on VPS

Job ID: 34469152

Budget: £10 – £20 GBP

I have been using shared hosting but transferring to my own VPS,

OS: Ubuntu

Installed Apache2
Installed lamp stack
Installed ION Cube
Installed sqlite3

Changed HTML folder owner

The issue I have is some of my panels which run a combination of html and PHP scripts work but others do not and just display either a white page or HTTP 500 error.

I'm wondering if there is a config file or PHP module I am missing.

Probably a simple fix for someone,

Thanks
