RESOLVED 500 Error when Installing

I am trying to install Piwik onto my server. Files such as “piwik.js” loads correctly, however, the php files return a 500 error. I am hosted on GoDaddy, I contacted them multiple times, and they assured me that there is no error on their side despite the message. I understand that sometimes a 500 error occurs when installing WordPress. If anyone encountered this error berfore, or could point me in the right direction, it would be greatly appreciated. Thank you in advance.

ETA:

I fixed the problem by setting all permission to 644.
