Fix a website with a php handling problem

We recently migrated a website from a Plesk VPS to a cPanel VPS. The site in question now only loads in plain text (refusing to pull and interpret a separate 'includes/[login to view URL]') for the images and it doesn't interpret the CSS stylesheet. <? $pageTitle = "111111"; $metaKeywords = "1111111"; $metaDescription = "1111111"; include 'include/[login to view URL]'; ?> I cannot diagnose this issue as I'm not a coder. HOWEVER, I did manage to temporarily fix this issue by changing the PHP 5 Handler in WHM from the default 'suphp' to 'dos'. I had to change this back, however, because the new handler is not compatible with all our other sites. Logins will be provided immediately. Payment will be disbursed immediately. This is probably an easy task and an easy change to earn quickly for someone literate in PHP. PRICE is negotiable depending on the complexity of the solution. Please message me for more details and to discuss your payment.
