You need to check whether the database connection information is correct, including host name, user name, Are the password, database name, port, etc. filled in correctly?

In addition, you can set the error prompt level in the php.ini file to facilitate finding code errors.

4. Check file upload restrictions

File uploading is a common way to publish articles, but in the process of publishing articles in the PHP background, you may encounter the problem of being unable to upload files. In this case, you need to check whether the restrictions on file upload in the PHP configuration file are reasonable. You can adjust the upload file size and upload file type restrictions by modifying the php.ini file.

If there is insufficient permission when publishing an article in the PHP background, you need to Check whether the directory or file where the article is published has the correct permissions set. You can use the chmod command to set appropriate permissions for a file or folder so that it can be accessed by the PHP backend.
