Deleted website data, couldnt log in, then began to get this error.

There have been a few times oveer the last couple of weeks where tye login screen essentially froze, prompting me to wonder if I had properly entered a password, and in some cases my legitimate password was denied… I have had some malware issues, so I assumed it was related, until I began to see this. I’m not exactly sure if this is a sort of bug report or just errors loading the html….
