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 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, check the relevant path settings:

//网站路径
'web_path' => '/网站所在的路径/'

If the website is installed in the root directory (such as a virtual Host www, public_html, htdocs and other directories), then it should be set to: 'web_path' => '/'; if installed under the directory /blog/, then 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 the two files cache/configs/system.php and api/checkcode.php is consistent, for example, the program version is utf -8 version, 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.
