HikeUp: you can login on your computer, but not the phone. May I assume that you usually use the phone, and use the computer to log-in to tapatalk approximately never, until it broke just now, and you tried it?
@Hikin_Jim started all this because he's having trouble logging in. It's his fault. I'm testing generally for user participation and complaints. So far there seems to be more problems than users. That's not good.
I finally got around to trying a different browser on my PC to login to crapatalk. I had been using Firefox and couldn't login lately. I tried MS Edge browser just now and it work no problem.
What about Firefox/Firefox settings could cause the issue?
There isn't anything wrong with Firefox. By switching to a new browser you have effectively cleared your cookies (since each browser has its own set), which worked around tapatalk's bug: they changed something so that their own cookie confuse them. Go back to firefox, delete tapatalk's cookies, and it'll work just fine.
