Damn it, I tried to upload all the files to my server at one time, there are more than 5000 files...
When the uploaded process is running at 20%, when uploaded the file src/XF/ControllerPlugin, and all the files uploaded with mistakes, it shows more than 80 files uploaded with errors.
I clicked to cancel the upload.
I used bt.cn tool to upload the xenforo files and control my server.
Now I can not open my site. And when I checked the status of the server, it shows it is under the attack of DDos and in Black Hole.
Thanks to that I made several copies of my website so I am not worried.
I read somewhere maybe because a big amount of uploading made my server provider thought that my server is under DDos attack and put my server in Black Hole. I will need to wait until my server provider cancels the Black Hole status(the server's official website says it is 2.5H) and then I can come to control my server and I can recover my website.
Maybe someone who has this kind of experience and can help me in this situation. Thank you so much for reading. Sorry for my not good english. And sorry I was a thief for this software, I just run my website for 1 month and now realized that I need to use a license website.
