How to solve the problem of phpcms background verification code not being displayed

Method 1: Check whether the gd library is enabled

1. Find the php.ini file and search for the extension=php_gd2.dll code (windows)

2. Then remove the previous ; symbol

centOS6.5 may need to install the gd library:

sudo yum install gd gd-devel php-gdsudo service php-fpm restart

Method 2:

The key point is to obtain verification The picture of the code is related to the global variable SITE_URL, which is the directory of the website, so just modify the website path variable 'web_path' in the cache/configs/system.php file.

In addition:

/caches/configs/system.php file also needs to be UTF-8 encoded.

Example (local domain name http://localhost)

If all files are in the root directory (such as htdocs under apache), at this time, the default access address should be is http://localhost/, then 'web_path'=>'/'. If the default access address of the website is not the root directory, you need to change the value of the variable 'web_path' to the new directory address, for example, in the root directory In the install subdirectory under the directory, it should be 'web_path'=>'/install/'. Note that the last '/' cannot be omitted.

Method 3:

Modify the encoding of the config.inc.php file to ANSI, which means it is consistent with the encoding of checkcode.php, because the encoding of checkcode.php is ANSI!

Find a UTF-8 text tool, such as UltraEdit-32, and save it as UTF-8 without BOM.
