Hmm, strange. I just checked in Safari on my computer (OSX High Sierra) and it's there. Can you try logging out and back in again to the forum?
I can see it on Safari too. Having said that, Safari has been doing some weird things lately (I have an older version 10.2). Like @snowbunny says, when I have a problem, completely exiting Safari and re-opening usually does the trick. That is the full sum of my technical knowledge, though.
This is annoying as it's still not working and I have logged in and out a dozen times I can't view new posts or recent ones. Any other suggestions techie people? xx
Sorry Helen, mad busy here right now. Have you tried emptying your cache? In the menu at the top of the screen, click Develop > Empty Caches. Other than that, it's really hard to debug something like this from elsewhere. Let me know what version of Safari you're running. You find this by clicking Safari > About Safari.
