I decided to give up aapanel. I don't know when I started using the BT host panel. Later, I switched to aapanel because of the binding collection problem. However, aapanel has too many problems, just like the BT panel. After debugging, there is no problem if you don't update it. As long as you update, there will be a mess of problems. I use aapanel on 25 servers, but every update takes me all night to debug. Sometimes I don't want to update, but if there is any major vulnerability that is not disclosed, it will cause great losses. Finally, I decided to give up aapanel and BT panel and use a more mature panel or only use the command line to manage the server. This can reduce a lot of my workload. Goodbye aapanel, goodbye BT
