Internal server error [500]

I’m doing a project on Smart greenhouse by interfacing Bolt wifi module and Arduino uno R3. The code seems fine to me but I keep getting Internal server error 500 . I’ve been trying for more than a week now. Please help!!

Well Internal server errors mostly originates from the server sides but i think in your case the problem may be from your side
Try the following:
1)clear your browser cache and cookies and then restart your browser
2)login from a different browser
3)use another network

This usually shows up if the server is unable to execute the PHP(Hypertext preprocesser).
Log inn to Cpannel and list of errors wil be shown and clear the errors.
