Hi folks. I'm sorry to hear that there are so many glitches going on at this time. There have been a lot of changes made on the site (migrating to Google Cloud, adding HTTPS, etc) which often can cause a few glitches in the process. So, both of these issues are known to our tech team, who is working out a fix. For the thread/number of posts issue, I would suggest clearing cache/cookies and trying again. I'll try running a thread rebuild as well to see if that helps. For the issue with New Likes, it redirects to the wrong page, however if you go to the right hand side of the page to where your Mini Statistics show, if you click on the number under where it says "Likes Received" it will take you to the correct page and your New Likes notifications will clear after that (once you refresh your page).
I know it's not ideal, but these are just a few workarounds that you can do in the meantime while our team works to get things fixed. Apologies for the inconvenience.
