I have the same problem.

I think these forums have been screwed up for months. If I visit this thread on my phone, I’m not logged in and the last post was 14 August. None of today’s posts show up. So I can’t even read my active threads from my phone because they’re in a different time-state than when I visit them on my desktop.
I read in another thread that “users with capitals in their username get apache errors when connecting to Waze forum”. Looking at the users above who’ve reported this issue (or no issue), it fits. Waiting for HQ to fix it…

When you go to the forum (with the desktop) without loging in is the same - you will see only old threads and posts.

still no workaround for this annoying problem?
Amit is looking into the apache errors that users with capitals in their usernames encounter with TT4.
This issue appears to have been fixed in their latest release.

Had downloaded & installed the update, still “no joy” … signed out of Waze everywhere, cleared the cache in TT4, tried again & was finally successful. Thanks.
Cheers!
Is it me only or does anybody have problem access the forum using TT4?
not just you, and not just TT4 
I hope waze rectify this soon as viewing from a mobile browser is no fun.
Clearing the cache does not help. Well, seems like we’re marooned 
I’m located in Malaysia
They are aware of the problem. I informed them this morning already. Not sure how much time they need…
Tapatalk is back…!
