@Leafbug @Kenneth Erwin Engelhardt guys, please check to see if there's a DDoS attack going on. I just got the log-in page instead of the log-in pop up again. This means the disappearing text box issue is happening again, and I had to delete and re-install Tor from scratch again.
This is the pop-up log-in box I usually get. When this disappears and I get the page, that means all text boxes are disabled again.
The only way around this issue to is re-install Tor from scratch.
