What if the php onethink CAPTCHA is not displayed? Onethink login verification code cannot be displayed

Analyze the causes and solutions:

1. In the case of non-php configuration problems, it has something to do with the encoding of the file itself. Utf-8, I have had this phenomenon because the file modified by notepad used directly on the server will not be found after that, and the problem can not be found. After that, all the modified files and CAPTCHA files were re-overwritten before they were solved.

2. Php GD does not support freetype.

3. The path is wrong.
