Can't reply and post and so on......

I'm very depressed that I can't use this forum. It can't be used most of the time, but sometimes it can be used. I've tried different browsers and related settings, but in vain. The main manifestations are as follows:

Can't reply
Topics tags inactive/unclickable (So I can't post also)
Follow inactive
Account settings inactive（Display blank）

After several months of observation, when it can't be used, it seems that some components of the website haven't been loaded. If it can be used, the opening and browsing speed will be very fast, but when it can't be used, the opening speed will be relatively slow. Therefore, I also tried to doubt the problem of network speed and tested it in 1000M optical fiber network environment，but it still can't be used. There are the same problems, including computers and Android phones, clearing all data, exiting the account and logging in again, but they can't solve the problem.

Now I can only take a chance to see when it can be used again. I can't do anything else.
