DedeCMS is an open source content management system that is widely used to build various types of websites. However, in the process of using DedeCMS, you may sometimes encounter some error prompts, which may affect the normal operation of the website and the user's access experience. This article will introduce some common DedeCMS error prompts and provide solutions to help you solve these problems.

1. Error message: Database connection error

1. Confirm the database information: First check whether the database host name, user name, password and database name in the database configuration file (/dede/common.inc.php) are correct and ensure they are consistent with your database settings.

2. Database permission issues: Check whether the database user has sufficient permissions to access and modify the database. You can grant corresponding permissions to database users in the database management tool.

3. Whether the database server is working properly: Check whether the database server is started and running normally. You can try to check whether the database server can connect normally through the ping command.

2. Error message: The file or directory does not exist

1. Confirm the file or directory path: Check whether the file or directory exists in the expected location. You can view the files and directories on the server through FTP tools or file managers.

2. File or directory permission issues: Make sure the file or directory has sufficient permissions so that DedeCMS can read and write to it. Typically, 755 permissions apply to directories and 644 permissions apply to files.

3. Error message: Template file error

1. Check the template file path: Confirm whether the template file is located in the correct path. You can view and edit template files in "Template Management" in the DedeCMS backend.

2. Check the template file syntax: If you make modifications in the template file, it may cause syntax errors. You can use the template syntax checker to check for and fix these errors.

4. Error message: Security sensitive character interception

1. Turn off security-sensitive character interception: In the "Global System Parameters" in the DedeCMS background, set the "Enable security-sensitive character interception" option to off. Please note that turning this option off may make your site more vulnerable to injection attacks, so proceed with caution.

2. Modify the security-sensitive character blocking rules: If you must enable security-sensitive character blocking, you can modify the security-sensitive character blocking rules according to the needs of your website. You can make corresponding modifications in "Security Settings" in "Global System Parameters".

5. Error message: Memory limit error

1. Increase the memory limit: You can increase the memory limit in the PHP configuration file (php.ini). Find the "memory_limit" option and increase its value appropriately.

2. Optimize queries and codes: During the development and use of DedeCMS, you can optimize codes and queries to reduce memory usage. There are some performance optimization plugins or tools you can use to help you find potential problems.
