The database crashed for half a day today, and will be maintained as soon as possible

I am very sorry. The database crashed for half a day today. It was a problem with the last database upgrade. It was not configured properly and crashed directly due to excessive load. It was mainly the previous problem. The database was occasionally overloaded, and it crashed for less than a minute in an hour. I suspected that it was an installation problem. I reinstalled it, and this situation still exists. The development boss has been too busy recently and has no time to go to Telegram. I can only check it slowly as an unprofessional. I may upgrade the configuration and try it recently. At the same time, due to the busy development boss, the progress of site function development will be delayed.
If it occasionally gets stuck, just wait a while and refresh.

I am very sorry. The website crashed for half a day. The problem left by the last database upgrade caused the database to crash. I am out and don’t have the server password, so I can’t maintain it. I will compensate everyone with a little magic to express my apology.
