错误号500

I am getting this console error:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

And also the content of my site is not visible. Since this is my fist time uploading and playing with these website stuff, I am not able to figure out where my mistake is.

The same thing runs perfectly on my localhost.

Here is the screenshot of the error:

The first error (404) indicates the image URL is not found, make sure you write the image URL properly.

For the second error, refer to this link as you may have an issue with file permissions or your .htaccess file
