PHP 7.1 and phplist

I switched the site from php 5.6 to php 7.1
I keep getting sent back to the login page for some reason.
I tried phplist 3.3 but it doesn’t help.
Is anyone using it under 7.1?


This sounds like a session or cookies problem.

phplist generally works with php 7+. My host has now upgraded to php 7.2


It seems I had to delete the cookie, now it is working OK
