phpcms v9 does not display Captcha how to do?

Recently, a friend encountered the problem that the management background login Captcha does not show after the website migration. Today, Phpcms V9 management background login Captcha does not show the solution. I hope it is useful for friends who learn phpcms.

Method 1: check the host environment to see if the gd library has been opened.

You can use a probe, or check the php.ini file, search for extension=php_gd2.dll, check if there is a comment symbol in front, and remove it.

Method 2: Check whether the configuration file is correct.

Open the configuration file: cache/configs/system.php and check where the path is set:

//Website Path

'web_path' => '/path where the site is located/'

If the site is installed in the root directory (e.g. www, public_html, htdocs, etc.), it should be set to: 'web_path' => '/'; if installed in the directory/blog/, it should be set to: 'web_path' => '/blog/'.

Method 3: Check the encoding format of the configuration file.

Mainly check whether the file encoding of cache/configs/system.php and api/checkcode.php is consistent. For example, if the program version is utf-8, then the utf-8 encoding format is selected when saving.

When modifying these files, it is recommended to use professional text editors such as editplus, EmEditor, Sublime Text, and avoid using the default text editor. Also note whether there is a BOM signature. You need to remove some of the editor's default BOM signatures.

This method also applies to Phpcms 2008, encountered before, modify the include/config.inc.php and checkcode.php file encoding is ANSI encoding format (or utf-8 encoding format) is good.
