What if the phpcms v9 background login verification code is not displayed?

The solution of not displaying the login verification code in the background of Phpcms V9 management

Recently, some friends have encountered the problem that the login CAPTCHA of the management background does not show after the migration of the website. Today, I would like to summarize the solution that the login CAPTCHA of Phpcms V9 management background does not show. I hope it will be useful for friends who learn phpcms.

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

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

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

If the website is installed in the root directory (such as virtual hosts 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 cache/configs/system.php and api/checkcode.php files are encoded all the time, for example, if the program version is utf-8, then choose the utf-8 encoding format when saving.

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

This method is also applicable to Phpcms 2008. As we have encountered before, it would be nice to modify both include/config.inc.php and checkcode.php files to ANSI encoding format (or utf-8 encoding format).
