Hello. Bit of strangeness happened to me yesterday. Running 3.6.6
Fired up phplist for the monthly newsletter, but when I tried to import new subscribers (via a csv file as I always do) I got the Invalid Security Token message. No matter what I do, reset the session, log out, empty the cache, I’m still getting the same error. I also get it when I try to export subscribers. Since I had not touched anything at all since last time it worked, I thought it was my ISP (one.com) that finally lost it so I made a clean installation on another server with another ISP, copied the DB and… still getting the same error. So it seems to be carried over with the DB.
I spent a couple of days trying to make it worked and I looked through the forums for any signs of anyone with a similar problem but without luck. Does anyone have any idea?
