I recently developed a project with ThinkPHP. After the local development and testing was completed and uploaded to the server, the first It opened normally for the first time, but when I refreshed the page, the error "Page debugging error, the page cannot be found, please try again " appeared. I was depressed, because the local setting define('APP_DEBUG', false) was running There's no problem, but why did it go wrong when I put it on the server? Baidu, Google still hasn't found a solution, and suddenly found that the project APP_Name/Runtime/Cache directory and APP_Name/Runtime/Logs directory did not have writable permissions, so I changed it decisively, F5, oh well, mom no longer has to worry about error messages!
