What should I do if phpcms v9 does not display the verification code?

Recently, a friend encountered the problem that the login verification code is not displayed in the management background after the website migration. Today I will summarize the solution to the problem that the login verification code is not displayed in the Phpcms V9 management background. I hope it will be helpful to those who learn phpcms. Friends are of some use.

Method 1: Check the host environment to see if the gd library has been enabled.

You can use a probe, or check the php.ini file, search for extension=php_gd2.dll, check whether 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 the relevant path settings:

//Website path

'web_path' => '/Website The path/'

If the website is installed in the root directory (such as virtual host www, public_html, htdocs and other directories), then it should be set to: 'web_path' => '/'; if installed in Under 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 select utf-8 encoding format when saving. .

When modifying these files, it is recommended to use professional text editors such as editplus, EmEditor, Sublime Text, etc. to avoid using text as the default text editor. At the same time, pay attention to whether it has a BOM signature. You need to remove some of the editor's default BOM signatures.

This method is also applicable to Phpcms 2008. I have encountered it before. Just modify the include/config.inc.php and checkcode.php file encodings to ANSI encoding format (or utf-8 encoding format).

The above methods are purely based on experience. If there are better ways or more ways, you can leave a message to discuss.
