Wamp running on the server, prompting for HTTP 500 Internal server exception

Run on the WAMP server, prompting for an HTTP 500 internal server error.
Excuse me,
It turns out that the normal cake Web site is running on the server.
After the original code download.
Run on a local wamp server,
Prompt for HTTP 500 Internal server error.

How does this work?
Please give me some details.
Thank you

is the server environment consistent with the original? You can view the server log in detail

In php.ini
Display_errors = On
This is a necessary condition for exclusion.

Visit the site, cut a picture to paste it out
You are widows system, at the same time press ALT + PRLSC key, the active window to the clipping version, open the paint, paste from the cut version, do the appropriate processing, save as JPG format (CSDN does not support BMP image upload). No additional software support required
------to solve the idea----------------------
When a 500 error occurs, the PHP program usually has an error, and the error message is generally visible when you open the error display function.
If it's not PHP's search problem, it's the server log.
The message from the Web page popup is generated by JS, due to PHP program error, resulting in the error message mixed in the JS code, resulting in JS code syntax error
