CodeIgniter 500 Internal Server Error on working site

Question

My site tourisminbhutan.com is build in Codeignitor & working fine but showing "500 Internal Server Error" in page header response code. Browser console & https://httpstatus.io/ showing error.

Here is the HTTP response I got:

HTTP/1.1 500 Internal Server Error =>

I can't figure out where is problem. Please help.

Answer 1

This should be your initial check list in case of 500 HTTP error code:

• Check the validity of *.htaccess files and file permissions.
• Check for any programming syntax errors.
• Check server error logs for any hidden errors.
• Make sure that you have the minimum requirement needed to operate Codeigniter Framework especially PHP version.

Please update me. Thank you
