config_global.php could not be found or the resolution cannot be accessed

Last night, I planned to revise the forum, but unfortunately, various problems occurred. The important thing is that I have never encountered this problem before. First, I backed up the website files through ftp and the database through database tools. Everything was so normal. Later, I changed the configuration files and configured them locally and opened www.zolfox.com/admin.php%E5%A5%B6%E5%A5%B6%E7%9A%84%E7%BB%93%E6%9E%9C%E5%87%BA%E7%8E%B0%E4%B8%8B%E9%9D%A2%E8%BF%99%E4%B8%AA%E9%94%99%E8%AF%AF%22%E9%85%8D%E7%BD%AE%E6%96%87%E4%BB%B6 "config_global.php" was not found or inaccessible. Please confirm that you have installed the program correctly."There was no mistake in changing the configuration file before. I was confused at that time. If there was any problem with the database user name, this error should not have occurred. So I went to the dz official website to find the answer. I found that many people encountered this problem. I have been playing dz for more than half a year. This is the first time I encountered it. Among them, a great god on the dz official website said that if your space provider does have config_global.php, download it back and see if the format inside is messy, such as no branches, no spaces, or messy, re-edit it. In some specific cases, such as non-binary upload and download and Notepad editing, the file format will be lost. The format of the lost file may not be readable. I found that the format in config_global.php was really messy, and I felt that this might be the problem, so I copied one from another place, passed through the configuration file, and reopened the one with the format unchanged.,,, https://www.zolfox.com/admin.php?% E7%AE%A1%E7%90%86%E5%91%98%E7%99%BB%E5%BD%95%E7%95%8C%E9%9D%A2%E7%A5%9E%E5%A5%87%E8%88%AC%E7%9A%84%E5%87%BA%E7%8E%B0%E4%BA%86%EF%BC%8C%E9%97%AE%E9%A2%98%E8%A7%A3%E5%86%B3%E5%91%BC%E5%91%BC%E3%80%82%E6%98%A8%E5%A4%A9%E5%B0%B1%E5%9B%A0%E4%B8%BA%E8%BF%99%E4%B8%AA%E9%97%AE%E9%A2%98%E8%BF%98%E6%9C%89%E4%B8%80%E4%B8%AA%E7%BD%91%E7%AB%99%E7%9A%84%E9%97%AE%E9%A2%98%E6%90%9E%E7%9A%84%E5%94%89%E3%80%82%E3%80%82%E3%80%82%E4%BB%8A%E5%A4%A9%E6%99%9A%E4%B8%8A%E6%8E%A5%E7%9D%80%E6%94%B9%E8%AE%BA%E5%9D%9B%EF%BC%8C%E7%9B%B8%E4%BF%A1%E7%94%A8%E4%B8%8D%E4%BA%86%E5%87%A0%E5%A4%A9%EF%BC%8C%E8%AE%BA%E5%9D%9B%E6%94%B9%E7%89%88%E5%AE%8C%E6%88%90%E5%B0%B1%E5%8F%AF%E4%BB%A5%E6%AD%A3%E5%BC%8F%E4%B8%8A%E7%BA%BF%E4%BA%86%E5%91%BC%E5%91%BC
