Authorized login kicks user out

Hello. Suddenly my phplist v3.6.8 lets me login as admin, then when I click on a configuration link or otherwise kicks me out of phplist. Logs show this happening:

xxxx.com - - [20/Jun/2022:14:06:42 -0400] “GET /lists/admin/?page=configure&tk=c9a46bf07fxxxxxxxxxeca1a89571f HTTP/1.1” 302 - “xxxxxx.com - xxx sex videos free hd porn Resources and Information.” “Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.5005.115 Safari/537.36”

I don’t have a clue. Does anyone?

Thanks.
