It's not easy to use WordPress as a personal website these days. Tell me about my troubles!

In recent days, I'm a little annoyed The traffic of the website has been declining for more than half a month After analyzing the statistical data, it is found that the traffic of Google and Shenma search engine has declined sharply, with the former half reduced and the latter almost a quarter reduced However, see Baidu and other search engines have no obvious change, how much in my heart there is a little bottom, not immediately mental breakdown Some time ago, I was so obsessed with trifles that I couldn't sit down and solve the problem seriously, so I had to drag on Just in August, the weather began to cool after the beginning of autumn, and the chores were basically handled, which made me calm down to deal with the trouble of the website This time, the problems are similar to hanging horses, because when you use the command "site: ew9z Com, you will know" to query on Google's search engine, and you will find a large number of messy URLs displayed on the results However, no viruses or Trojans were detected by various scanning and diagnostic tools such as Baidu platform and Google search console Looking at the relevant data, we found that the search traffic began to decline from August 1, and Baidu and Google's page collection also decreased significantly Since there is no server maintenance for a long time, Linux related commands and operation technologies become very unfamiliar, which requires at least a few days to be familiar with and calm down There's no way For tomorrow's bread, we have to work it out Want to steal a lazy at the beginning, ask the technical personnel of Western Digital to deal with it But unfortunately, the other side just hung the server to observe and watched the work order process being processed, but the result was very unreliable Later, I put forward a work order to see if I can roll back the cloud snapshot to the middle of July But the reply is that the data has been overwritten and cannot be rolled back The shortcuts are all blocked We can only rely on ourselves In the past, when I met with problems, I would go to relevant websites abroad to find information, and generally I could find answers quickly Unfortunately, it's hard to get over that wall these days, which wastes a lot of time Occasionally I turned over to find something in a hurry, but it didn't work very well What should I do? The website always has to go on, there is no way back You can only check one by one First, download the latest version of WordPress, and after decompression, completely overwrite the two folders WP admin and WP include; next, check the files in the root directory to see if there are any invalid files after update, and delete seven or eight redundant files; then delete the redundant code in the header file under the theme It was late at night after these work, so I had to wash and sleep After breakfast the next day, continue to work Checked the recently changed files on the server with relevant commands, and no exception was found At this time, when I went to Google search, I found that the number of pages included had increased from 16000 to 19000, and there were a lot less cluttered URLs I thought, it's not far from the final solution.
